A block of mass m is kept on a platform which starts from rest with constant acceleration g/2 upward, as shown in the figure. Work done by normal reaction on block in time t is:
A man of mass () is sitting in a train movingwith velocity . He observe that a block of mass is moving towards him with velocity . Then the kinetic energy of block w.r.t man is (Assume )
