A man is on a bosun chair attached to a frictionless massless pulley and is holding onto the other end of a rope. (at ground level)
a. What is the force he must pull himself up at if he is to move at a constant speed?
Is the set up T + T = mg?
b. If instead the rope is held by someone else, what is the force needed to pull him up at a constant speed?
And is this set up as T = mg?
c. What is the force exerted by the ceiling on the system for both cases?
This one I am lost on since I need to do a free body diagram for each case.
I don't understand why there is such a difference, in essence.
