A man of mass 40 kg is standing on a block A of mass 140 kg. He pushes another block B of mass 60 kg on the ground, so that they are set in motion. [Assume no friction between the block and the ground. The man does not slide on A ]
(A) Speed of block A is three times that of block B immediately after the interaction
(B) Speed of block B is three times that of block A immediately after the interaction
(C) Distance travelled by block B is three times that of block A in the same time
(D) Distance travelled by block B is nine times that of block A in the same time.
