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...

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

Renee is on Spring Break and pulling her 21-kg suitcase through the airport at a constant speed of 0.47 m/s. She pulls on the strap with 120 N of force at an angle of 38° above the horizontal. Assume the ground to be flat, Draw a FBD showing the forces on the suitcase. Find the acceleration of the suitcase. Determine the normal force experienced by the suitcase. Determine the total resistive force (friction) experienced by the suitcase. Find the coefficient...
