Question

Derive an expertion for kinetic energy of an object​

Answer 1

Answer:

Suppose a body of mass M is moving with velocity v. It is brought to rest by applying a retarding force F. Suppose it traverses a distance s before coming to rest. Kinetic energy of body, KE = Work done by retarding force to stop it.

Answer 2

Answer:

Hii...

Explanation:

Let us consider an object of m which is at rest lying on a table.

Let A force F acts on the object which moves the object through a distance S.

The work done=F×S

W=F  net ×S-------(1)

Let the work done on the object causes a change in its velocity from u to V and let a be the acceleration.

Hope it helps you.
