A light rope fixed at one end to a wooden clamp on the ground passes over a frictionless pulley and hangs on other side. The rope makes an angle of
30° with the ground and wooden clamp come out of the ground if an upward force greater than 360 N acts on it. The maximum acceleration of 60 kg
man in upward direction so he can climb safely is
(g = 10 m/s2)
0
1 m/s2
o
2 m/s2
0
4 m/s2
0
45 m/s2

Explanation:
A light straight fixed at one end to a wooden clamp on a ground passes over fixed pulley and hangs at the other sides. It makes an angle 30
o
with the ground. A boy weighing 60 kg climbs up the rope. The wooden clamp can tolerate upto vertical force 360 N.find the maximum acceleration in the upwards direction with which the boy can climb safely. The friction of pulley and wooden clamp may be ignored (g=10 m/s
