A rod of length L is geld vertically on a smooth horizontal surface. The top end of the rod is given a gentle push. At a certain instant of time when the rod makes an angle of 37° with horizontal the velocity of the centre of mass of the rod is 2m/s. The velocity of the end of the rod in contact with the surface at that instant is 1) 2 m/s 2) 1 m/s 3) 4 m/s 4) 1.5 m/s
