Two masses 2m and m are connected by an inextensible light string. The string is passing over a light frictionless pulley. The mass 2m is resting on a surface and mass m is hanging in air as shown in the figure. A particle of mass m strikes the mass m from below and with a velocity v_(0) and sticks to it. In another case a particle of mass m strikes the mass m with a velocity v_()) from top and sticks to it. Calculate the ratio of velocities of mass m just after collision in first and second case.
