To hoist himself into a tree, a 66.0-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 366 N. Neglect any friction between the rope and the branch, and determine the man's upward acceleration.
Concern yourself with the force diagram. The rope has two ends, with tension 366N.Total upward force on the man: 2*366
Downward force: mg or 66*9.8N
solve for a.
