Answer to Question #3623 in Mechanics | Relativity for shivam

Question

A car body of mass M has four disc wheels each of mass m.
It rolls on a horizontal track having uniform velocity of mass centre of car is V.
Determine the total work done by the system to move the car by 1metere.

Answer 1

If the car rolls with uniform velocity on a horizontal plane its kinetic and potential energy is constant. Hence, there is no any work done by the system.
