Answer 2

Explanation:

The amount of work required to stop a moving body is equal to the kinetic energy of the object

• In other words, the work done is equal to the change in K.E. of the object! This is the Work-Energy theorem or the relation between Kinetic energy and Work done. In other words, the work done on an object is the change in its kinetic energy. W = Δ(K.E.)
