Question

A body of mass 10kg is moving whith velocity 10 m/s.the work done to stop the body is

Answer 1

Answer:

Hey buddy your answer

Explanation:

The kinetic energy of a body of mass m=10kg moving at v=10m/s is

E=(1/2)mv²

After being stopped, the kinetic energy of the body has been transferred to work done (assuming no frictional loss), and has nothing left.

So we can find

Work done=loss/reduction in kinetic energy.

E=1/2*10*10*10=500 J
