A small man is sitting in a bosun chair that dangles from a massless rope, which runs over a massless frictionless pulley and back down to the mans hand. The combined mass of the man and the chair is 95kg. with what force magnitude must the man pull on the rope if he is to rise?
Mass = 95Kg
a = ?
v = ?
F = ?
I didnt get very far with this one, I drew one F.B.D for the man and got the following:
Nothing in the X direction
y--------T+v = -mg
Heres a link to a drawing

Should i draw another F.B.D for the mans hands on the rope?
