Three balls `A, B` and `C` of same mass `m` are placed on a frictionless horizontal plane in a straight line as shown. Ball `A` is moved with velocity `u` towards the middle ball `B`. If all the collisions are elastic, find the final velocities of all the balls.

Text Solution

Verified by Experts

A collides elastically with B and comes to rest but B starts moving with velocity u

A collides elastically with B and comes to rest but B starts moving with velocity u

`therefore ` Final velocities
`V_(A)=0`,
`V_(B)=0 and V_(C)=u`
