In perfect inelastic collision :
(A) Both Momentum and K. E. are conserved
(B)
Both Momentum and Kinetic Energy are not conserved
(C) Momentum is conserved and Kinetic Energy is not conserved
(D) Momentum is not conserved and Kinetic Energy is conserved​

Answer 1

Answer:

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions.

Suppose two similar trolleys are traveling toward each other with equal speed. They collide, bouncing off each other with no loss in speed. This collision is perfectly elastic because no energy has been lost.
