Is it possible to have a collision in which the whole of KE is lost?

Is it possible to have a collision in which the whole of K.E is lost.

In any perfectly inelastic collision, is whole of KE lost ?

Discuss the possibility of a particular type of collision ini which the particles have more kinetic energy after the collision than before. It is known as super elastic collision. Will momentum remain conserved in such a collision

If two objects collide and one is initially at rest (a) is it possible for both to be at rest after collision ? (b) is it possible for any one to be at rest after collision.?

Two particles of masses 0.5 kg and 0.25kg moving with velocity 4.0 m // s and -3.0m // collide head on in a perfectly inelastic collision. Find the velocity of the composite particle after collision and KE lost in the collision.
