Question

hey track and moving with same Momentum which of them has more kinetic energy justify your answer​

Answer 1

Hey mate here is your answer :

Work done =Force×distance= Change in kinetic energy. Both the truck and the car had same kinetic energy and hence same amount of work is needed to be done. As retarding force applied is same for both, therefore, both the truck and the car travel the same distance before coming to rest .

Hope it helps.
