    What is the man's upward acceleration when hoisting himself into a tree?

    I thought the lifting force required is still reduced

    What is the man's upward acceleration when hoisting himself into a tree?

    I believe that because there is a pulley, the question isn't as simple as "he weighs more than the force he exerts so therefore he must not be lifted"; have you learned about the physics of pulleys? I think that is the area of physics this question might be about...

    Don't worry, I'm not this stupid, I was mimicking the other commenter hahaha!

    What is the man's upward acceleration when hoisting himself into a tree?

    Firstly: WMAN = mg = 72x9.8 = 705.6N So force required to lift the man is 705.6N. Surely if he pulls on the rope with a force of 358N, he won't be lifted off of the ground at all?
