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

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 speed of ball of mass 2m just after collision (for the first time) is over

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.

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

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. After the first collision, what is the total loss in kinetic energy of the balls?

Two balls of mass m and 2m are attached with strings of length 2L and L respectively. They are released from horizontal position. Find ratio of tensions in the string when the acceleration of both is only in vertical direction :
