A man in a bosun chair dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. Combined mass of the man and chair is 95.0 kg. What force must the man pull on the rope if he is to rise (a) with constant velocity and (b) with an upward acceleration of 1.3 m/s2? The same man in the bosun chair dangles from a massless rope, which runs over a massless, frictionless pulley and back down to a man standing on the ground, pulling the rope. What force magnitude must the man on the ground pull for the man in the bosun chair to rise (c) with a constant velocity and (d) with an upward acceleration of 1.3 m/s2? What is the magnitude of the force on the ceiling from the pulley system in (e) part a, (f) part b, (g) part c, and (h) part d.
