A ball of mass m moving with velocity V,...

A ball of mass `m` moving with velocity `V`, makes a head on elastic collision with a ball of the same moving with velocity `2 V` towards it. Taking direction of `V` as positive velocities of the two balls after collision are.

A

`-V and 2V`

B

2V and -V

C

V and -2 V

D

`-2V and V `

Text Solution

Verified by Experts
