A car and a lorry are moving with the same kinetic energy. Both are brought to rest with the same opposing force applied through brakes. Which one will stop within a less distance ?

Explanation

As soon as the lorry and the car come to rest, their kinetic energies becomes zero. Hence the change in kinetic energy (= work done by the brakes) will be the same for both the vehicles. Now, work done = force `xx` displacement . As force applied is the same both the car and the lorry will cover the same distance before coming to rest.
