Ok, I already posted this a few days ago but I am bringing it back because i don't quite understand
a man sits in a bosuns 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 must the man pull on the rope to rise with a constant velocity
so..
T=-mg/2
T = 465.5N
this doesn't make sense because if he is to rise any amount, he would have to exert more force that gravity does..Wouldnt he?
