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 balls having masses m and 2m are fastened to two light strings of same length shown in the figure. The other ends of the strings are 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 balls having masses m and 2m are fasrtened to two light strings of same length (figure). The other ends of the strings are 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. Point A is the lowest point at which either ball can reach The position at which the balls will collide for the first time

The strings are kept in the same horizontal line and the system is released from rest. The collision between the balls is elastic. Point A is the lowest point at which either ball can reach The speed of ball of mass 2m just after collision (for the first time) is over

The ball is released when the string is horizontal. The collision between the ball and the block is head - on elastic. The velocities of the ball and the block immediately after collision

A ball moving with speed u collides with an identical ball at rest. The velocities of two balls after collision are (If the collision is elastic):

Two identical balls, each of mass m , are tied with a string and kept on a frictionless surface. Initially, the string is slack. They are given velocities 2u and u . in the same direction. Collision between the balls is perfectly elastic. What is the final loss in kinetic energy of the balls?
