A ball of mass M moving with velocity V0 on a frictionless surface strikes the first of two identical balls, each of mass m = 2 kg, connected by a massless spring with spring constant k = 1 kg/s2 (see Figure). Consider the collision to be central and elastic and essentially instantaneous.(a) Find the minimum value of the mass M for the incident ball to strike the system of two balls again.(b) How much time will elapse between the two collisions?
