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. It makes an angle with the ground. A man weighing (60 kg) 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 at the tree branch. Take g = 10

Let T be the tension in the rope.
The upward force on the clamp is, T sin= T/2
The maximum tension that will not detach the clamp from the ground is:
T/2 =360N
T = 720 N
T – 600 = 60a
where a is the acceleration of man in upward direction.
