An object moves at a constant speed of 6 m/s. This means that the object:

Answers

Answer:

The object moves 6 m in every second.

Explanation:

When we say something is constant, we simply means that it does not change with time i.e it the same through out irrespective of time.

Now, let us answer the question given above.

An object moving at a constant speed of 6 m/s. Has the following characteristics:

1. The object moves 6 m in every second.

2. The object is not accelerating since it has a constant speed. Therefore, the acceleration of the object is zero.

3. The object is moving as it covers a distance of 6 m in every second.

4. The speed remains the same since the speed of object is constant.

Thus, the right answer to question is: The object moves 6 m in every second.

The skid marks left by the decelerating jet-powered car The Spirit of America were 9.60 km long. If the car's acceleration was -2.00 m/s2, what was the car's initial velocity.

Answers

Answer:

The car's initial velocity is 195.96 m/s

Explanation:

Given;

the length of the mark, x = 9.6 km = 9600 m

acceleration of the car, a = -2 m/s²

Apply the kinematic equation below

v² = u² + 2ax

where;

v is the final velocity = 0

u is the initial velocity

simplify the equation and you will obtain;

0 = u² + 2ax

0 = u² + 2(-2)(9600)

0 = u² - 38400

u² = 38400

u = √38400

u = 195.96 m/s

Therefore, the car's initial velocity is 195.96 m/s

The electrostatic force that a charged particle, q1q1 , exerts on another charged particle, QQ , at a distance r1r1 , is FF . A second charged particle, q2q2 , exerts the same force FF on QQ at half the distance r1r1 . What is the value of q1q1 in relation to q2q2 ?

Answers

Answer:

q₁ / q₂ = 4

Explanation:

In this exercise we must use Coulomb's law

         F = k q₁q₂ / r²

For this case the electric force is

        F = k q₁ Q / r₁²

indicate that another particle q₂ has the same force on Q, but for r₂ = r₁ /2

        F = k q₂ Q / r₂²

we equate the two equations

           q₁Q / r₁² = q₂ Q / r₂²

we substitute r₂

        q₁Q / r₁² = q₂ Q / (r₁/2)²

        q₁ = q₂ 4

the relationship between the two charges is

         q₁ / q₂ = 4

Answers

A child slides down a hill on a toboggan with acceleration of 1.8 m/s2. if she starts from rest, how far has she traveled in: 2 seconds

Answer:

2.4 m

Explanation:

From the question above,

Applying equation of motion,

s = ut+at²/2....................... Equation 1

Where t = time, u = initial velocity, a = acceleration,  s = distance.

make s the subject of the equation,

Given: a = 1.8 m/s²,  t = 2 seconds, u = 0 m/s (from rest)

Substitute these value into equation 1

s = 0(2)+1.8(2²)/2

s = 1.2(4)/2

s = 2.4 m.

Hence she has traveled 2.4 m

Answer:

4.0m/s

A baseball is released at rest from the top of the Washington Monument. It hits the ground after falling for 6 s. What was the height from which the ball was dropped

Answers

Answer:

Total height (s) = 176.4 m

Explanation:

Given:

Initial velocity (u) = 0 m/s

Time taken (t) = 6 sec

Acceleration due to gravity = 9.8 m/s²

Find:

Total height (s)

Computation:

s = ut + [1/2]gt²

s = (0)(6) + [1/2][9.8][6²]

s = 176.4 m

Total height (s) = 176.4 m

difference between universal law of gravitation and acceleration due to gravity​

Answers

Explanation:

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G(capital g). The relation between G and g is not proportional. That means they are independent entities.

G and g

In physics, G and g can be related mathematically as –

\(g=\frac{GM}{R^{2}}\)

Where,

1=g is the acceleration due to the gravity of any massive body measured in m/s2.

2=G is the universal gravitational constant measured in Nm2/kg2.

3=R is the radius of the massive body measured in km.

4=M is the mass of the massive body measured in Kg.

If a NASCAR driver is driving around a track, and he travels 600 miles in 3 hours, what is his average speed in miles per hour (mph)? __________ mph

Answers

Answer:

200 mph.

Explanation:

If a NASCAR driver travels 600 miles in 3 hours, the way to calculate the speed at which the car is driving comes from dividing the distance factor by the time factor.

Thus, we must divide 600 by 3 (600/3), which gives 200 as result. Thus, if in 3 hours he travels 600 miles, in one hour he will travel 200 miles, which means that his average speed is 200 mph.

2. How long will it take for a ball thrown vertically upward with an initial velocity of
480 km/h to reach its maximum height?

Answers

Answer:

13.33 seconds

Explanation:

At maximum height, the equation of motion becomes:

v = u + at

Since the object was thrown vertically, the initial velocity (u) is zero and the acceleration (a) becomes the acceleration due to gravity (10 m/s2). The equation becomes:

v = at

v = 480 km/hr = 133.333 m/s

    10t = 133.333

       t = 133.333/10

           t = 13.33 seconds.

The time for the ball thrown vertically with a velocity of 480 km/hr to reach the maximum height is 13.33 seconds.

Melissa and Rory live near a bike trail, 21 km apart. They plan to meet at a park mid-way between their homes. They start from their homes at the same moment, and ride toward each other. Both ride at 7 km/hour. Melissa’s dog Jessie knows this routine. He starts with Melissa, and runs at 18 km/hour toward Rory. When he reaches Rory, he turns around and runs toward Melissa. He reaches Melissa, turns around and runs toward Rory again, and so on, until Melissa and Rory meet. How many kilometers did Jessie run?

Answers

Answer:

27km.

Explanation:

Jessie will run for a duration of time, which is the time it takes for Melissa and Rory to meet each other.

Together combined, Melissa and Rory runs at 14km/h. The bike trail is 21km, so it will take 1.5 hours.

Jessie runs at 18km/h, so Jessie will run 18 * 1.5 = 27km.

Your friend's car is stuck in the snow. You push very hard and become very 1 tired but the car won't move. Did you do work?

Yes, work was done

No, work wasn't done​

Answers

Answer:

Yes you  worked

Explanation:

You may have not seen a good outcome but you did put effort in.

When a force is applied on the car and it doesn't move then it simply means

work wasn't done.

The formula for work is given below:

Work = Force ₓ Displacement

For work to have been done , the applied force must cause the object to

change its position(displacement).

In situations where the force applied doesn't cause a change in position then work can't be calculated. This means no work was done on the car despite the applied force causing him to be tired.

Titus drives his jetski a distance of 1000 meters in 7.045 seconds. How fast was he moving in meters per second? How fast was he moving in miles per hour?

Answers

Answer:

a) v = 141.9 m/s

b) v = 317.4 miles/h

Explanation:

a) How fast was he moving in meters per second?

[tex] v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s [/tex]

Hence, the jet ski is moving at 141.9 meters per second.

b) How fast was he moving in miles per hour?

[tex] v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s*\frac{3600 s}{1 h}*\frac{1 mile}{1609.34 m} = 317.4 miles/h [/tex]      

Therefore, the jet ski is moving at 317.4 miles per hour.

A car goes from 40 m/s to 30 m/s in 5 sec. What is its acceleration?

If acceleration is constant, then it is equal to the average acceleration.

NEED HELP ASAP Carlos is analyzing the results of a recent scientific study about gravity.

Calculate the percent error of the experimental versus accepted values of gravity. 5.01% 4.38% 2.66% 9.27%

Answers

Answer:

4.38 %

Explanation:

Given that,

The experimental value of gravity is 10.24 m/s²

The general accepted value of gravity is 9.81 m/s²

We need to find the percent error of the experimental versus accepted values of gravity.

The formula used to find the percentage error is given by :

[tex]\%=\dfrac{|\text{original value-calculated value}|}{\text{original value}}[/tex]

Putting all the values:

[tex]\%g=\dfrac{|9.81-10.24|}{9.81}\times 100\\\\\%g=4.38 \%[/tex]

So, the percentage error is 4.38 %.
