A truck and a car are moving with equal velocity

Asked by admin @ 03/08/2021 in Physics viewed by 310 People

A truck and a car are moving with equal velocity. If equal retarding force is applied on each, then on applying the brakes both will stop after certain distance

Answered by admin @ 03/08/2021

If F is the force of friction and s is the distance travelled by truck or car, then work done against force of friction is at the cost of kinetic energy of vehicles. i.e. Since kinetic energy and the retarding force on both the vehicles are same, therefore both will come to rest after travelling equal distances.
