Two small rings each of mass ‘m’ are connected to a block of same mass ‘m’ through inextensible light strings. Rings are constrained to move along a smooth horizontal rod. Initially system is held at rest (as shown in figure) with the strings just taut. Length of each string is ‘l’. The system is released from the position shown. Find the speed of the block (v) and speed of the rings (u) when the strings make an angle of theta = 60^(@) with vertical.

Consider two skaters A and B initially at rest on ice -(friction is negligible) with A holding a ball. A has greater mass than B and the ball has some significant mass. A throws the ball to B. B catches it and throws it back to A who catches it again. The magnitudes of the skater’s (excluding ball) final velocities, A momentum and kinetic energies (denoted below as v, p and K respectively) are related as
