If `u_(1)` and `u_(2)` be the initial velocity and `v_(1)` and `v_(2)` be the final velocities of the colliding partical then we define coefficient of restitution `e` as:
`e = (v_(1) - v_(2))/(u_(1) - u_(2))`
For perfectly inelastic collision 'e' is

A

zero

B

1

C

`lt 1`

D

`gt 1`

Text Solution

Verified by Experts

The correct Answer is:
