In an elastic collision

A

the initial kinetic energy is equal to the final kinetic energy

B

the final kinetic energy is less than the initial kinetic energy

C

the kinetic energy remains constant

D

the kinetic energy first increases then decreases

Text Solution

Verified by Experts

The correct Answer is:
A
Due to deformation, kinetic energy decreases and during restoration, kinetic energy increases so that `K_(f) = K_(i)`.
