Question

Show that in perfectly elastic collision in one dimension when a body

collides with another body in rest there is always some loss of kinetic

energy.​

Answer 1

Explanation:

Two identical objects (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved.
