A cricket ball of mass 150 grams is moving in some direction with a speed of 12 m/s.

Two particles of mass 1 kg and 0.5 kg are moving in the same direction with speed of 2 m//s and 6 m/s respectively on a smooth horizontal surface. The speed of centre of mass of the system is

A 60 kg body moving with speed 12 m/s collides inelastically with another body of mass 50 kg moving in same direction with speed 2 m/s. After collision the 50 kg body moves with a speed of 10 m/s. The value of coefficient of restitution (e) is :-

A cricket ball of mass 150 g is moving with a speed of 12ms^(-1) and is hit by a bat so that the ball is turned back with velocity of 20ms^(-1) if duration of contact between bat and ball is 0.01 s then:

A ball of mass 2kg moving with speed 5m/s collides directly with another ball of mass 3kg moving in the same direction with speed 4m/s. The coefficient os restitution is 2/3. Find the velocities of both ball after the collision.

If two balls each of mass 0.06 kg moving in opposite directions with speed 4 m//s collide and rebound with the same speed , then the impulse imparted to each ball due to other is

A cricket ball of mass 150 kg is moving with a velocity of 12 m//s and is hit by a bat so that ball is turned back with a velocity of 20 m//s . The force of the blow acts for 0.01 s on the ball . Find the average force exerted by the bat on the ball.
