A 10 kg block is gently put on a moving plank with velocity 1 m s on a frictionless horizontal ground surface And in due time the block starts with the plank at 1 m s The work done by the external force which maintains the constant speed of Planck The coefficient of friction between plank and the block is 0 4 take g 10 m s A 100 J C 10 J B 50 J D 5 J
