A 40 kg boy climbs a rope that passes over an ideal pulley. The other end of the rope is attached to a 60 kg weight placed on the ground. What is the maximum upward acceleration the boy can have without lifting the weight ? If he climbs the rope with upward acceleration 2 g, with what acceleration the weight will rise up ?
