Embibe Experts Solutions for Exercise 5: Exercise 5.5

A particle strikes elastically with another particle with velocity $v$. After collision, it moves with half of the velocity in the same direction. Find the velocity of the second particle if it is initially at rest.

A bullet of mass $m$ moving with velocity $v$ strikes a block of mass $M$ at rest and gets embedded into it. The kinetic energy of the composite block will be

A particle of mass $m$ moving with a speed $v$ hits elastically another stationary particle of mass $2m$ on a smooth horizontal circular tube of radius $r.$ The time in which the next collision will take place is equal to

A tennis ball is thrown from a height $h$ above the ground. If the coefficient of restitution is $e,$ what height will the ball achieve after the third collision?

From a point on smooth floor of a room, a toy ball is shot to hit a wall. The ball then returns back to the point of projection. If the time taken by ball in returning is twice the time taken in reaching the wall, find the coefficient of restitution for collision of ball with wall.

Five identical balls each of mass $m$ are placed adjacent to each other at rest on a smooth horizontal floor. An another identical ball moving with speed $v$ collides elastically with the left most ball as shown in figure. After collision(s)
