Define coefficient of restitution

A particle is dropped on Earth from height R (radius of earth) and it bounces back to height h. If the coefficient of restitution of collision is sqrt(2/3) , then find h.

A partical falls from a height h upon a fixed horizontal plane and rebounds. If e is the coefficient of restitution, the total distance travelled before rebounding has stopped is

Choose the correct options A block of mass m moving at a speed of u collides with another block of mass 2 m at rest. The lighter block comes to rest after the collision. The coefficient of restitution is

A sphere of mass 'm' moving with velocity 'v' collides head-on on another sphere of same mass which is at rest. The ratio of final velocity of second sphere to the initial velocity of the first sphere is (e is coefficient of restitution and collision is inelastic)

A ball moving with velocity 2 ms^(-1) collides head on with another stationary ball of double the mass. If the coefficient of restitution is 0.5 , then their velocities (in ms^(-1) ) after collision will be

A 1 kg ball moving with a speed of 6" ms"^(-1) collides head - on with a 0.5 kg ball moving in the opposite direction with a speed of 9" ms"^(-1) . If the coefficient of restitution is (1)/(3) , the energy lost in the collision is

A mass 2m moving with some speed is directly approaching another mass m moving with double speed. After some time, they collide with coefficient of restitution 0.5 Ratio of their respective speeds after collision is

A moving block having mass m, collides with another stationary block having mass 4m. The lighter block comes to rest after collision. When the initial velocity of the lighter block is v, then the value of coefficient of restitution (e) will be

A body of mass 1 kg moving with velocity 5 m/s collides with another body of mass 2 kg moving with velocity 1.5 m/s in opposite direction. If the coefficient of restitution is 0.8, their velocities aftter collision respectively are
