Two smooth spheres A and B, of equal radius but ofmasses m and M, are free to move on a horizontal table. Ais projected with speed u towards B which is at rest. Onimpact, the line joining their centres is inclined at anangle θ to the velocity of A before impact. If e is thecoefficient of restitution between the spheres, find thespeed with which B begins to move. If A’s path afterimpact is perpendicular to its path before impacttan2θ= eM- m/M- m
