Question
A light straight fixed at one end to a wooden clamp on a ground passes over a fixed pulley and hangs at the other side. It makes an angle 30° with the ground. A boy weighing 60 kg climbs up the rope. The wooden clamp can tolerate up to vertical force 360 N. Find the, maximum acceleration in the upward direction with which the boy can climb safely. The friction of pulley and wooden clamp may be ignored 
The correct answer is:
