In figure, determine the character of the collision. The masses of the blocks, and the velocities before and after are given. The collision is

A

perfectly elastic

B

Partially inelastic

C

Completely inelastic

D

This collision is not possible

Text Solution

Verified by Experts

The correct Answer is:
A

Ans.(1)
Linear momentum is conserverd and
`e=("Speed of separation")/("Speed of approach")=(1.4+0.6)/(1.8+0.2)=1`
So, collision of perfectly elastic.

On a smooth carrom board. A coin located at (4,6) is moving in negative y- direction with speed 3m//s is being hit at that point by a striker moving along negative x- axis . The line joining centre of the coin and striker just before the collision is parallel to x- axis. After collision the coin goes into the hole located at origin. Mass of the striker and the coin is equal. Considering the collision to be elastic, find the velocity ( in vector form ) of the stricker before the collision and after the collision.
