PLS HELP. A flatbed car of a train moves 8 m/s to the east. A jogger runs along to top the flatbed car (which is not very safe) with a velocity of 6 m/s to the west. How fast is the jogger moving?

Answers

Answer:

2 m/s

Explanation: Given that a flatbed car of a train moves 8 m/s to the east. A jogger runs along to top the flatbed car (which is not very safe) with a velocity of 6 m/s to the west.

Since the jogger is moving in an opposite direction to the direction of the train, and velocity is the distance covered in a specific direction, the jogger will be moving at a velocity relative to the velocity of the train.

Velocity = (8 - 6) m/s

Velocity = 2 m/s

Therefore, the jogger will be moving at the speed of 2 m/s

The electric motor of a model train accelerates the train from rest to 0.620 m/s in 21ms. The total mass of the train is 825 g. find the average power delivered to the train during its acceleration.

Answers

Explanation:

Average power = change in energy / change in time

P = ΔE / Δt

P = (½ mv²) / t

P = (½ (0.825 kg) (0.620 m/s)²) / (0.021 s)

P = 7.55 Watts

In many locations, old abandoned stone quarries have become filled with water once excavating has been completed. While standing on a 10.0 m high quarry wall, Clarence tosses a piece of granite into the water below. If Clarence throws the rock horizontally with a velocity of 3.0 m/s how far out from the edge of the cliff will it hit the water?

Answers

Answer:

Explanation:

Let us calculate the time of flight first using the formula;

Velocity = Displacement/Time

Time = Displacement/speed

Time = 10.0/3

Time = 3.33secs

Next is to calculate how far out from the edge of the cliff it will hit the water. To get that, we will use the equation of motion;

S= ut+1/2gt²

u is the initial velocity = 0m/s

g is the acceleration due to gravity = 9.81m/s

S = 0 + 1/2(9.81)(3.33)²

S = 4.905*3.33*3.33

S = 54.39m

Hence it will hit the water at 54.39m from the edge of the cliff

Answer:

It will hit the water at [tex]4.28m[/tex] off the cliff

Explanation:

Applying kinematic relations along vertical direction

[tex]y = V_0t + \frac{1}{2}a_yt^2[/tex]

where,

[tex]a_y = g[/tex]

therefore,

[tex]y = 0 + \frac{1}{2}gt^2[/tex]

The time taken

[tex]t = \sqrt{\frac{2y}{g}}\\\\t = \sqrt{\frac{2*10}{9.8}}\\\\t = 1.428s[/tex]

The horizontal distance

[tex]x = V_yt\\\\x = 3*1.428\\\\x = 4.28m\\\\[/tex]

a. Zero
b. 100 m/s
C. 200 m/s
d. None of the above
3. In problem two. What would be the average speed? (2 pts)
1

Answers

Answer:

100m/s

Explanation:

velocity = displacement/time

The average velocity of the race car around the circular track in the given time is 62.8m/s.

Hence, option D) None of the above is the correct.

What is Average Velocity?

Average velocity is simply the displacement of a particle or object over time. It is the rate of change of position of an object with respect to time.

It is expressed as;

Velocity = displacement / time

It can also be expressed as;

Velocity = circumference / time = 2πr / t

Given the data in the question;

Radius of the track r = 500mTime elapsed t = 50sAverage velocity V = ?

To determine the average velocity, we substitute our values into the expression above.

V = 2πr / t

V = ( 2 × 3.14 × 500m ) / 50s

V = 3140m / 50s

V = 62.8m/s

The average velocity of the race car around the circular track in the given time is 62.8m/s.

Hence, option D) None of the above is the correct.

What is a species?

A species simply refers to a biological classification of related organisms that have the same (similar) characteristics and they are capable of mating (breeding) with one another in a cycle (different seasons).

Based on the diagram above, we can logically deduce that the organisms shown are species of elephants and they look similar due to the following points:

They both have a single tail.They both have ears.They both have four legs.They both have tusk.

However, an obvious difference between them is the number of tusk.

What is the smallest part of a chemical compound that has all the properties

B. A mineral

D. A molecule

Answers

Answer:

D. A Molecule

Explanation:

The smallest particle of a compound that still has the properties of the compound is a molecule. It is composed of two or more bonded atoms.

The smallest part of a chemical compound that has all the properties of that compound is a molecule (option d)

In the world of chemistry, substances are composed of tiny units called atoms, and these atoms bond together to form chemical compounds.

Option A, a nucleus, refers to the central core of an atom and consists of protons and neutrons. While essential for an atom, a nucleus alone does not represent a complete chemical compound.

Option B, a mineral, is a naturally occurring inorganic substance with a specific chemical composition and a definite atomic structure. However, minerals are not the smallest parts of a chemical compound.

Option C, an atom, is the fundamental building block of matter. It consists of a nucleus (containing protons and neutrons) surrounded by electrons. While atoms are crucial for forming compounds, they are not the smallest unit that retains all the properties of a compound.

Therefore, the correct answer is Option D, a molecule. A molecule is a group of two or more atoms bonded together, representing the smallest part of a chemical compound that possesses all the characteristics and properties of that compound.

Hence the correct option is (d).

Answer:

7.5 seconds

Explanation:

Given that a dog starts at the origin and runs forward at 6 m/s for 1.5 s

From speed formula

Speed = distance/time

Substitute speed and time into the formula

6 = distance/1.5

Distance = 6 × 1.5 = 9 m

and then turns around to fetch the ball by

running backward at 7 m/s for 3 s. If the dog runs.

Calculate the distance covered

Distance = 7 × 3 = 21 m

This means that the dog ran beyond the original position.

The elapsed distance = 21 - 9 = 12m

back to the origin at 4 m/s, by covering distance 12 m

Calculate the time.

Speed = distance/time

Time = 12/4 = 3s

The time elapsed between the start and when he returns with the ball will be:

T = 1.5 + 3 × 3

T = 7.5 seconds

A 95kg clock initially at rest on a horizontal floor requires a 560N horizontal force to set it in motion. After the clock is in motion, in horizontal force of 650N

Answers

Complete Question

A 95 kg clock initially at rest on a horizontal floor requires a 650 N horizontal force to set it in motion. After the clock is in motion, a horizontal force of 560 N keeps it moving with a constant velocity. Find the coefficient of static friction and the coefficient of kinetic friction.

Answer:

The value for static friction is [tex]\mu_s = 0.60[/tex]

The value for static friction is [tex]\mu_k = 0.70[/tex]

Explanation:

From the question we are told that

The mass of the clock is [tex]m = 95 \ kg[/tex]

The first horizontal force is [tex]F _s = 560 \ N[/tex]

    The second horizontal force is    [tex]F _k  =  650  \  N[/tex]

Generally the static frictional force is equal to the first  horizontal force

So

     [tex]F _s  =  m  *  g  *  \mu_s[/tex]

=>   [tex]560  =  95  *  9.8  *  \mu_s[/tex]

=>    [tex]\mu_s =  0.60[/tex]

Generally the kinetic frictional force is equal to the second horizontal force

So

      [tex]F _k  =  m  *  g  *  \mu_k[/tex]

      [tex]650 =  95  *  9.8  *  \mu_k[/tex]

     [tex]\mu_k =  0.70[/tex]
