Answer:
Explanation:
Given that,
Initial speed of the car, u = 14 m/s
Finally, it comes to rest, v = 0
Time, t = 5.6 s
We need to find the average acceleration of the car during this time interval. We know that,
So, the acceleration of the car is 
in the opposite direction of motion.
Energy is transferred.
<h3>What is Work?</h3>
Every time labour is performed, energy is transmitted, as shown by the definition of work in physics. Work is the result of the displacement's magnitude and the component of force acting in that direction.
What are 3 types of work done?
- Positive
- Negative
- Zero work done.
Work is the result of force and distance, or the force exerted over a specific distance. In other words, Work = Force x Distance.
Joules are used to measure work.
1. Positive Work: Positive work is when a force moves an object in that direction. The motion of a ball descending toward the earth while it is displaced in the direction of the force of gravity is an illustration of this type of labour.
2. Negative Work: The work is said to be negative if the force and the displacement are in the opposing directions. For instance, if a ball is thrown high, its displacement will also be upwards, while the force from the earth's gravity will be downward.
3. Zero Work: When the force and displacement directions are parallel to one another, there is no work done on the item by the force.

Hi Pupil Here's Your answer :::
➡➡➡➡➡➡➡➡➡➡➡➡➡
When an object is moving with uniform circular motion, the centripetal acceleration of the object
.
Because the body is moving with a uniform velocity and hence, there might not be any acceleration due to it.

Hope this helps .......
Gravitational force is reduced by:
B. The square of the distance..... hope that helps ;)
