(a) When the sphere 1 is released from horizontal position, then from energy conservation, potential energy at height Or Or Since, all collisions are elastic, so velocity of sphere 1 is transferred to sphere 2, then from 2 to 3 and finally from 3 to 4. Hence, just after collision, the sphere 4 attains a velocity equal to |
