A ball of mass m, moving with a speed `2v_0` collides inelastically (e>0) with an identical ball at rest. Show that for head-on collision, both the balls move forward.

A ball of mass m, moving with a speed 2v_0 collides inelastically (e>0) with an identical ball at rest. Show that For a general collision, the angle between the two velocities of scattered balls is less than 90^@ .

A block of mass m moving at a speed v collides with another block of mass 2 m at rest.The lighter block comes to rest after the collision.Find the coefficient of restitution.

A moving ball of mass m undergoes a head - on elastic collision with another ball of mass 2 m at rest .Show that the colliding ball loses 8/9 th of its K.E. energy after collision.

A ball of mass M_1 collides elastically and head on with another ball of mass M_2 initially at rest.When will transfer of energy from first body to second body he maximum?

A cricket ball of mass 150 g moving with a speed of 126 km/h hits at the iddle of the bat, held firmly at its position by the batsman. The ball moves straight back to the bowler after hitting the bat. Assurming that collision between ball and bat is completely elastic and the two remain in contact for 0.001 s, the force that the batsman had to apply to hold the bat firmly at its place would be

A cricket catches a ball of mass 150 g in 0.1 s moving with a speed of 20 ms^-1 . Then the experiences a foce of

A boy travelling in an open car moving on a levelled road with constant speed tosses a ball vertically up in the air and catches it back. Sketch the motion of the ball as observed by a boy standing on the footpath . Give explanation to support your diagram.

Two identical ball bearings in contact with each other and resting on a frictionless table are hit head-on by another ball bearing of the same mass moving initially with a speed V. If the collision is elastic, which of the following (Fig. 6.14) is a possible result after collision ?

A tennis ball of mass 6.0 (10 *-2) kg is moving with a speed of 62ms-1 . Calculate the wavelength associated with this moving tennis ball.

A ball of mass 100 g moving with a velocity of 10ms^-1 is stopped by a boy in 0.25sec. Calculate the force applied by the boy to stop the ball.
