Two identical balls are interconnected with a massless and inextensible thread. The system is in gravity free space with the thread just taut. Each ball is imparted a velocity `v`, one towards the other ball and the other perpendicular to the first, at `t=0`. Then,

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.

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
