A rod of length L is held vertically on a smooth horizontal surface. The top end of the rod is given a gentle push. At at certain instant of time when the rod makes an angle 37∘ with horizontal the velocity of COM of the rod of 2 m/s. The velocity of the end of the rod in contact with the surface at that instant is
