A truck and a car moving with the same kinetic energy are brought to rest by the application of brakes which provide equal retarding forces. The distance moved by the truck, in coming to rest, will then be _ the distance moved by car.

Solution

Explanation
The value of displacement or distance travelled, $s$ is same for both truck and car as they are moving with the same kinetic energy.
Also they are brought to rest by the application of brakes which provides equal retarding forces.
Therefore, both the truck and the car will travel the same distance before coming to rest.
Hence, the distance moved by the truck, in coming to rest, will then be the same as the distance moved by car.
