To hoist himself into a tree, a 72.0-kg man ties one end of a nylon rope around his waist and throws the other end over a branch of the tree. He then pulls downward on the free end of the rope with a force of 373 N. Neglect any friction between the rope and the branch, and determine the man's upward acceleration. Use g =9.80 m/sec2.
