Question

# 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 358 N. Neglect any friction between the rope and the branch, and determine the man's upward acceleration.

We're given:

$m=72.0\,\text{kg}\\ F_p=358\,\text{N}$

If we neglect the friction, we have to calculate the acceleration of the man.
