1.	Derive expression for kineic energy
Answer» r a body of MASS ‘m’ at rest. Let a constant force F act on the body PRODUCING anacceleration ‘a’ for a DISTANCE ‘s’. Let the velocity of the body be changed to v.In this case, initial velocity = 0.Final velocity = vUsing, Work DONE F×s = mas = => work done = 1/2 mv²By definition this work done is equal to the KINETIC energy._________________________
