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, 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 1 kg block situated on a rough incline is connected to a spring of spring constant 100N m^-1 as shown in Fig. 6.17. The block is released from rest with the spring in the unstretched position. The block moves 10 cm down the incline before coming to rest. Find the coefficient of friction between the block and the incline. Assume that the spring has a negligible mass and the pulley is frictionless.

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?

The triangular block is moving on a frictionless surface with 3 m//s^2 towards right such that the mass m does not slide on the tiangular block.Find the coefficient of friction between mass m and the block. .

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 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:

A block of mass M is places in the top of a biggr block of mass 10 M as shown in fig.All the surfaces are frictionless.The system is released from rest.Find the distance moved by the bigger block at the instant the smaller block reaches the ground. .
