A particle of mass $m$ is dropped from rest from a height $h_0$ on a horizontal floor. The coefficient of restitution between the floor and particle is $e$. Maximum height attained by the particle after second collision is

If the coefficient of restitution is 0.5, what is the percentage loss of energy on each rebounding of a ball dropped from a height?

In perfectly elastic collision

Two balls each of mass 1 kg moving in opposite directions with speed 15 m/s collides and rebounds with the same speed. The magnitude of impulse imparted to each ball due to other is

A small ball is dropped from a height of 10 m on horizontal floor. If the coefficient of restitution between ground and ball is 0.5 then maximum height to which ball will rise after second collision with ground is

A ball of mass M falls from a height h on a floor which has coefficient of restitution e. The height attained by the ball after three rebounds is

A ball of mass 4 kg moving on smooth horizontal surface makes head-on elastic collision with another ball of mass m at rest. If, after collision first ball moves in the same direction with one-fourth of its velocity before collision, the mass of second ball is

A ball of mass 0.5 kg is dropped from a height of 40 m. The ball hits the ground and rises to a height of 10 m. The impulse imparted to the ball during its collision with the ground is (Take g = 9.8 m/s²)

A ball is dropped from a height of 10 m hits the ground. If coefficient of restitution between the ball and ground is $\frac{1}{2}$, then the percentage loss of energy after the first collision will be

A small ball of mass 2m, moving with speed v collides with another stationary ball having mass 5m. If the lighter ball comes to rest after collision, then the value of coefficient of restitution (e) will be

Two balls of equal mass of 4 kg each are moving with velocity 4 m/s towards each other collides inelastically. If the coefficient of restitution is 0.5, then the loss in kinetic energy due to collision will be

A particle of mass $m_1$, making a head on elastic collision with another stationary ball of mass $m_2$. If $m_1$ rebounds with half of its original speed then $\frac{m_1}{m_2}$ is
