Two sphere `A` and `B` of equal masses lie on the smooth horizontal circular groove at opposite ends of diameter and at the end of time 't','A' impings on 'B' . If 'e' is the coefficient of restitution, the second impinge will occur after a time

Two identical spheres A, B are in a smooth horizontal circular smooth groove at opposite ends of a diameter. A is projected along the groove and it impinges on B in a time interval T. Let e be the coefficient of restitution, the

Two equal sphere A and b lie on a smooth horizontal circle groove at opposite ends of a diameter. At time t= 0,A is projected along the groove and tis first implings on B at time t = T_(1) and again at time t = T_(2). If e is the coefficient of restitution, the ratio T_(2)//T_(1) is

A wedge of mass M and angle alpha rests on a smooth horizontal plane. A smooth sphere of mass m strickes it in a direction perpendicular to its inclined face and rebounds. If the coefficient of restitution is e, find the ratio of the speed of the sphere just before and just after the impact.

Two particles A and B of mass 3kg and 4kg moving on a smooth horizontal surface with speed 5m//s and 2m//s respectively collides each other. Coefficient of restitution is e=(1)/(2) , then Velocity of B after collision

A ball after freely falling from a height of 4.9m strikes a horizontal plane. If the coefficient of restitution is 3/4 , the ball will strike second time with the plane after

Two particles A and B of mass 3kg and 4kg moving on a smooth horizontal surface with speed 5m//s and 2m//s respectively collides each other. Coefficient of restitution is e=(1)/(2) , then Velocity of A after collision
