List of top Physics Questions on Elastic and inelastic collisions asked in AP EAPCET

Two identical balls P and Q having velocities $0.7 m s^{-1}$ and $-0.4 m s^{-1}$ respectively are colliding in one dimension elastically. The velocities of P and Q after the collision respectively are:

A moving block having mass $m$ collides with another stationary block of mass $5m$. After the collision, the block with mass $m$ comes to rest. If the initial velocity of the block with mass $m$ is $V$, then the value of the coefficient of restitution ($e$) is:

Two balls \(A\) and \(B\), of masses \(M\) and \(2M\) respectively collide each other. If the ball \(A\) moves with a speed of \(150\;\text{m s}^{-1}\) and collides with ball \(B\), moving with speed \(v\) in the opposite direction. After collision if ball \(A\) comes to rest and the coefficient of restitution is \(1\), then the speed of ball \(B\) before it collides with ball \(A\) is
