1. To hoist himself into a tree, a 67.2-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 361 N. Neglect any friction between the rope and the branch, and determine the man's upward acceleration.
2. f=ma3.I thought that the amns weight at the other end would be
67.2(9.81) = 659.232N
and this would make an overall force of 298.232 but not up, down,
this would give an acceleration of -4.42 ms-2
but this is wrong
any help?
