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 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 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_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 ball of 0.1 kg makes an elastic head on collision with a ball of unknown mass that is intitially at rest.If the 0.1 kg ball rebound at one third of its original speed ,what is the mass of the other ball?

A 2 kg ball moving at 24 ms undergoes inelastic head on collision with a 4 kg ball moving in the opposite direction at 48 ms. If the coefficient of restitution is 2/3, their velocities in ms-after impact are

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^@ .

The bob A of a pendulum released from 30^@ to the vertical hits another bob B of the same mass at rest on a table as shown in Fig. 6.15. How high does the bob A rise after the collision ? Neglect the size of the bobs and assume the collision to be elastic.

Two identical ball bearing 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 shown in the figure. If the collision is elastic, which of the folloiwng shown in the figure is a possible result after collision ?

A ball is dropped from a height of 90 m on a floor. At each collision with the floor, the ball loses one tenth of its speed. Plot the speed-time graph of its motion between t = 0 to 12 s.

A body of mass 5 kg strikes another bodfy of mass 2.5 kg initially at rest.The bodies after collision coalesce and begin to move as a whole with a KE of 5 j.the KE of the first body before collision is:
