If you were trying to knock someone over by throwing a ball of mass m and speed v at them, should you throw a rubber bouncy-ball, or lump of clay? Hint 1: Clay does not bounce well. Hint 2: Both the bouncy ball and clay would be the same mass, travelling at the same speed. Throwing the bouncy ball would be better. There is not enough information to tell. Throwing the lump of clay would be better. Either object wouldn't make a difference. BONK STOP IT!
