An elastic ball of mass ‘m’ is suspended from a fixed point by an inextensible string. A small particle of same mass m, moving downwards at an angle of 37^(@) with the vertical lits the ball directly with the velocity v_(0). If the coefficient of restitution is 4//5, (i) find the velocity of the ball just after the impact. (ii) determine the impulsive tension(i.e impulse) in the string at the instant of collision.
