A light rope fixed at one end of a wooden clamp on the ground passes over a tree branch and hangs on the other side (shown in the figure). It makes an angle of 30°with the ground. A man weighing 60kg wants to climb up the rope. The wooden clamp can come out of the ground if an upward force greater than 360N is applied to it. Find the maximum acceleration in the upward direction with which the man can climb safely. Neglect friction on the tree branch. Take,
