An 11-kg monkey is climbing a massless rope attached to a 15-kg log over a frictionless tree limb. (a) With what mini- mum acceleration must the monkey climb up the rope so that it can raise the 15-kg log off the ground? If, after the log has been raised off the ground, the monkey stops climbing and hangs on to the rope, what will now be (b) the monkey's acceleration and (c) the tension in the rope?

Therefore, the minimum acceleration of the monkey, required to lift the log is 3.56 m/s2.

Therefore, the acceleration of the monkey when he has stopped climbing up the tree is 1.50 m/s2.

Therefore the tension in the rope is 124.5 N .
