Q1:

For perfectly elastic bodies, the value of coefficient of restitution is

A zero

B 0.5

C 1.0

D between 0 and 1.

ANS:C - 1.0

For elastic bodies,

Velocity of approach = velocity of separation.

v2 - v1 = u1 - u2, so both are cancelling.

We are getting the value coefficient of restitution e = 1.
