Two pendulums each of length `l` are initially situated as shown in Fig. The first pendulum is released and strikes the second. Assume that the collision is completely inelastic and neglect the mass of the string and any frictional effects. How high does the centre of mass rise after the collision?

A ball of mass m moving horizontally at a speed v collides with the bob of a simple pendulum at rest. The mass of the bob is also m. If the collision is perfectly inelastic and both balls sticks, the height to which the two balls rise after the collision will be given by:

Two balls having masses m and 2m are fastened to two light strings of same length l figure. The other ends of the strings ar fixed at O. The strings are kept in the same horizontal line and the system is released from rest. The collision between the balls is elastic. a. Find velocities of the balls just after their collision. b. How high will the balls rise after the collision.

Two massless string of length 5 m hang from the ceiling very near to each other as shown in the figure. Two balls A and B of masses 0.25kg and 0.5kg are attached to the string. The ball A is released from rest at a height 0.45m as shown in the figure. The collision between two balls is completely elastic. Immediately after the collision, the kinetic energy of ball B is 1 J The velocity of ball A just after the collision is

A uniform rod of length L lies on a smooth horizontal table. The rod has a mass M . A particle of mass m moving with speed v strikes the rod perpendicularly at one of the ends of the rod sticks to it after collision. Find the velocity of the centre of mass C and the angular, velocity of the system about the centre of mass after the collision.

Three solid spheres each of mass m and radius R are released from the position shown in Fig. What is the speed of any one sphere at the time of collision?
