The figure shows a man sitting in a bosun's chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of man and chair is 83.1 kg. With what force magnitude must the man pull on the rope if he is to rise (a) with a constant velocity and (b) with an upward acceleration of 1.27 m/s2? (Hint: A free-body diagram can really help.) Problem continues below....
The figure shows a man sitting in a bosun's chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of man and chair is 66.7 kg. With what force magnitude must the man pull on the rope if he is to rise (a) with a constant velocity and (b) with an upward acceleration of 1.34 m/s2? (Hint: A free-body diagram can really help.) Problem continues below....
A bosun’s chair is a device used by a boatswain to lift himself to the top of the mainsail of a ship. A simplified device consists of a chair, a rope of negligible mass, and a frictionless pulley attached to the top of the mainsail. The rope goes over the pulley, with one end attached to the chair, and the boatswain pulls on the other end, lifting himself upward. The chair and boatswain have a total mass M = 95.7...
help :( (diagrams 2,3,4 are included here ) QUESTION 7 A box is at rest on a horizontal, frictionless table. Horizontal force F1 points along the positive x-axis; when it is the only force acting on the box, the box accelerates at 6.75 m/s. Force F3 is also horizontal; it has magnitude 2.85F, and acts at an angle 22.6° to the direction of F1. If forces F1 and F3 act on the box at the same time, find the magnitude...
