Using a simply pulley/rope system, a crewman on an Arctic expedition is trying to lower a 6.82-kg crate to the bottom of a steep ravine of height 28.6 meters. The 50.3-kg crewman is walking along holding the rope, being careful to lower the crate at a constant speed of 1.50 m/s. Unfortunately, when the crate reaches a point 15.9 meters above the ground, the crewman steps on a slick patch of ice and slips. The crate immediately accelerates toward the...

1. An Atwood Machine consists of weights attached to the two ends of a pulley. For this machine, the pulley is a thin disk which has a radius of 2m, mass 1 is 8 kg and mass 2 is 5 kg, and both masses start at 5 meters above the ground. When we release the system from rest: How fast will mass 1 be moving right before it hits the ground? b. How fast will mass 2 be moving right...

The fiqure 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 78.4 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 1.42 m/s2? (Hint: A free-body diagram can really help.) Problem continues below...
