A mountain climber encounters a gap in an ice field. The opposite side of the gap is 2.75m lower, and is separated horizontally by a distance of 4.1m. To cross the crevasse, the climber gets a running start and jumps in the horizontal direction. (A) What is the minimum speed needed by the climber to safely cross the gap? (B) What is the climber's velocity right before landing?​

Answers

Answer:

A) 5.5 m/s

B) 9.2 m/s

Explanation:

A) Given in the y direction:

Δy = 2.75 m

v₀ = 0 m/s

a = 9.8 m/s²

Find: t

Δy = v₀ t + ½ at²

2.75 m = (0 m/s) t + ½ (9.8 m/s²) t²

t ≈ 0.75 s

Given in the x direction:

Δx = 4.1 m

a = 0 m/s²

t = 0.75 s

Find: v₀

Δx = v₀ t + ½ at²

4.1 m = v₀ (0.75 s) + ½ (0 m/s²) (.75 s)²

v₀ ≈ 5.5 m/s

B) Find vᵧ.

v² = v₀² + 2aΔy

vᵧ² = (0 m/s)² + 2 (9.8 m/s²) (2.75 m)

vᵧ ≈ 7.34 m/s

Find v.

v² = vₓ² + vᵧ²

v² = (5.5 m/s)² + (7.34 m/s)²

v ≈ 9.2 m/s

2. What is the distance the object moves from 0 to 9 seconds?

3. What displacement did the object have between 2 s and 9 s?

4. What was the object's average velocity over the first 5 seconds?
5. How many times does the object change direction of travel? (time zero
does not count and standing still does not count as a direction change)

Answers

Answer:

Explanation:

1). To calculate the instantaneous velocity of the object, we will calculate the slope of the line CD.

  Since line CD is a straight line, therefore, slope = 0

  Hence instantaneous velocity = 0

2). Distance of the object when it moves from 0 to 9 seconds

    = Distance traveled from (A to B + B to C + C to D + D to E)

    = 3 + (3 + 0.5) + 0 + 0.5

    = 7 m

3). Displacement = Distance between initial and the final positions of the object

    = 3 - 0

    = 3 m

4). Average velocity = [tex]\frac{\text{Displacement}}{\text{Time}}[/tex]

                                 = [tex]\frac{0.5}{5}[/tex]

                                 = 0.1 m per sec

5). Direction changes have been seen at t = 2 sec and t = 4 sec.

   Hence object changed its direction of travel 2 times.

What force is required to accelerate a 6 kg bowling ball at 2 m/s/s forward?

Answers

Answer:

12N

Explanation:

Force = mass * acceleration.

6 * 2 = 12

Taking into account the Newton's second law, the force required to accelerate a 6 kg bowling ball at 2 m/s² forward is 12 N.

In first place, acceleration in a body occurs when a force acts on a body. There are two factors that influence the acceleration of an object: the net force acting on it and the mass of the body.

Newton's second law states that this force will change the speed of an object because the speed and / or direction will change. These changes in velocity are called acceleration.

So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object.

Mathematically, Newton's second law is expressed as:

F= m×a

where:

F = Force [N] m = Mass [kg] a = Acceleration [m/s²]

In this case, you know:

F= ? m= 6 kg a= 2 m/s²

Replacing:

F= 6 kg× 2 m/s²

Solving:

F= 12 N

Finally, the force required to accelerate a 6 kg bowling ball at 2 m/s² forward is 12 N.

Pictured is an animal cell and a plant cell. Which organelle labeled in the plant cell produces the energy for the cell?

Answers

Answer:

Mitochondria

Mitochondria. Mitochondria are double membrane-bound cell organelles responsible for the supply and storage of energy for the cell.

Explanation:

The organelle labeled as "mitochondria" in the plant cell produces the energy for the cell through the process of cellular respiration.

What are mitochondria?

Mitochondria are organelles found in most eukaryotic cells. They are often referred to as the "powerhouses" of the cell because their main function is to produce energy in the form of ATP (adenosine triphosphate) through a process called cellular respiration.

Mitochondria have an outer membrane and an inner membrane with folds called cristae. The space between the two membranes is called the intermembrane space, while the space inside the inner membrane is called the mitochondrial matrix. The mitochondrial matrix contains enzymes and other molecules needed for the metabolic reactions of cellular respiration.

Cellular respiration is a process that converts glucose and oxygen into ATP, which is the primary energy source for cells. Mitochondria play a key role in this process by breaking down glucose through a series of chemical reactions that ultimately produce ATP. The energy stored in ATP molecules can then be used by the cell for various cellular processes, such as muscle contraction, protein synthesis, and the maintenance of the cell's membrane potential.

In addition to their role in ATP production, mitochondria are also involved in other important cellular functions, such as calcium signaling, apoptosis (programmed cell death), and the synthesis of certain lipids and heme groups. Mitochondrial dysfunction has been implicated in a number of diseases, including Parkinson's disease, Alzheimer's disease, and diabetes.

Therefore, Through the process of cellular respiration, the organelle in the plant cell known as the "mitochondria" generates the energy for the cell.

Answers

Answer:

The net force on the box is 2N and it will make the box to move in a leftward direction

Explanation:

We should understand first of all that forces are vectors. This means that they have both magnitude and direction.

The next thing we will need to do is to set a coordinate system. Let the leftward forces be negative while the rightward forces are positive.

That means that the equivalent forces on the box will be -5N + 3N = - 2N

Hence, the net force on the box is 2N and it will make the box to move in a leftward direction

The acceleration of his brain is most closely equal to * 1 point 0.4g 4g 40g 400g

Answers

Answer:

1) acceleration is increased by a factor of four 4X

2) the acceleration increases a factor of 2X

3) the correct answer of 400g

Explanation:

This is a kinematics exercise, where you use the velocity equation to obtain the acceleration, with the final velocity equal to zero.

           v² = v₀² + 2 a x

           0 = v₀² + 2 a x

           a = - v₀² / 2 x

           

In the case of wanting to give the acceleration as a function of g, we can find the relationship between the two quantities

         a / g = - v₀² / (2 x g)

Let's answer the different questions about this equation

1. The initial velocity is doubled, how much the acceleration is worth

           

       a/g = - (2v₀) 2 / 2xg

       a = 4 (-v₀² / 2xg) g

acceleration is increased by a factor of four 4X

2. if the stopping distance is reduced by 2, that is, x = x₀ / 2

we substitute

        a/g = (- v₀² / 2g) 2/x

         

        a =2  (-v₀² / 2x₀g)  g

       

therefore the acceleration increases a factor of 2X

3. the initial velocity of the hockey player is v₀ = 20 m / s and the stopping distance is

x = 5cm = 0.05m

we calculate the acceleration

        a / g = - 20² / (2 0.05)

        a / g = - 4000 / g

        a / g = - 4000 / 9.8 = 408

        a = 408 g

the correct answer of 400g, the value matches exactly if g = 10 m / s2 is taken

Two point charges +3 micro coulomb and +8 micro coulomb repel each other with a force of 40N . If a charge of -5 micro coulomb is added to each of them, then the force between them will become?

Answers

Answer:

1 N

Explanation:

Given that two point charges +3 micro coulomb and +8 micro coulomb repel each other with a force of 40N.

Let us first calculate the distance between the two point charges

F = (KQq)/r^2

Where K = 9.0 × 10^9Nm^2C^-2

40 = (9×10^9 × 3×10^-6 × 8×10^-6)/r^2

Make r^2 the subject of formula

r^2 = 0.216/40

r = sqrt (5.4^-3)

r = 0.0735 metres

If a charge of -5 micro coulomb is added to each of them, then the force between them will become?

Using the same formula again

F = ( KQq)/r^2

Where Q = 8 - 5 = +3 × 10^-6 C

q = 3 - 5 = - 2 × 10^-6 C

F = ( 9×10^9 × 3×10^-6 × 2×10^-6 )/5.4×10^-2

F = 0.054/0.054

F = 1 N

The force of attraction between the two point charges will be 1 N

3. A model rocket is launched straight upward at 58.8 m/s.
a. How long does it take for the rocket to reach its peak height?
b. what is the total time of flight of the model rocket ?
c. what is the peak height of the rocket from the ground ?

Answers

Answer:

a). 6 seconds

b). 12 seconds

c). 176.4 meters

Explanation:

a). Equation to be applied to calculate the time taken by the rocket to reach at the peak height,

   v = u - gt

where v = final velocity

u = initial velocity = 58.8 m per sec

g = gravitational pull = 9.8 m per sec²

t = duration of the flight

At the peak height,

v = 0

Therefore, 0 = 58.8 - (9.8)(t)

t =  [tex]\frac{58.8}{9.8}[/tex]

 = 6 seconds

b). Total time of flight = 2(Time taken to go up)

                                    = 2×6

                                    = 12 sec

c). Formula to get the peak height is,

   [tex]h=ut-\frac{1}{2}gt^2[/tex]

   h = (58.8)6 - [tex]\frac{1}{2}(9.8)(6)^2[/tex]

      = 352.8 - 176.4

      = 176.4 meters
