A window washer sits in a bosun's chair that dangles from a massless rope that runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of man and chair is=93.0kg.

With what magnitude of force 1 must he pull downward to raise himself at constantspeed?

With what magnitude of force 2 must he pull downward to raise himself with an upward acceleration =1.70m/s2?
