A car and a truck have the same kinetic energy

Asked by admin @ 06/08/2021 in Physics viewed by 293 People

A car and a truck have the same kinetic energies at a certain instant while they are moving along two parallel roads. Which one will have greater momentum?

pls do reply

Answered by admin @ 06/08/2021

Explanation:

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.
