Three identical balls are connected by light inextensible strings with each other as shown and rest over a smooth horizontal table. Length of each string is l . At moment t = 0 , ball B is imparted a velocity v_(0) perpendicular to the strings and then the system is left on its own. If collision between the balls is completely inelastic, then

Two identical balls each of mass m interconnected by a small light inextensible string are kept on a smooth horizontal surface. One of the balls is pushed towards the other with a speed v_(0) find the loss of K.E. of the ball. What will be the final velocities of the balls ? (e=1).

Two identical small balls are interconnected with a light and inextensible thread having length L. The system is on a smooth horizontal table with the thread just taut. Each ball is imparted a velocity v , one towards the other ball and the other in a direction that is perpendicular to the velocity given to the first ball. (a) After how much time the thread will become taut again? (b) Calculate the kinetic energy of the system after the string gets taut.

A ball of mass in m= 1 kg is hung vertically by a thread of length l = 1.50 m . Upper end of the thread is attached to the ceiling of a trolley of mass M= 4 kg . Initially, the trolley is stationary and it is free to move along horizontal rails without friction. A shell of mass m=1 kg, moving horizontally with velocity v_(0) = 6 m//s collides with the ball and gets stuck with it. As a result, the thread starts to deflect towards right. The velocity of the combined body just after collision is

In the figure shown, the two identical balls of mass M and radius R each, are placed in contact with each other on the frictionless horizontal surface. The third ball of mass M and radius R/2, is coming down vertically and has a velocity = v_(0) when it simultaneously hits the two balls and itself comes to rest. The each of the two bigger balls will move after collision with a speed equal to
