In figures (a), (b) and (c) shown, the objects A, B and C are of same mass. String, spring and pulley are massless. C strikes B with velocity u in each case and sticks it. The ratio of velocity of B in case (a) to (b) to (c) is

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.
