A crate of mass m1 = 11.4 kg is pulled by a
massless rope up a 36.9° ramp. The rope passes over an ideal pulley
and is attached to a hanging crate of mass m2 =
16.3 kg. The crates move 2.70 m, starting from rest. Find the final
speed of the sliding crate if the incline is frictionless.
Explanation
Since energy is conserved and nonconservative forces do no work,
mechanical energy is conserved. Let the y-axis point

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...

A crate of mass m1 = 12.4 kg is pulled by a massless rope up a 36.9° ramp. The rope passes over an ideal pulley and is attached to a hanging crate of mass m2 = 16.3 kg. The crates move 1.40 m, starting from rest. If the frictional force on the sliding crate has magnitude 22.6 N and the tension in the rope is 121.5 N, find the total work done on the sliding crate.

A 6kg bucket of water is being pulled straight up by a string at a constant speed. I determined that the tension on the string was F = ma F = (6kg * 9.8 m/s2) * 0a F = 58.8 N Now its asking At a certain point the speed of the bucket begins to change. The bucket now has an upward constant acceleration of magnitude 3 m/s2. What is the tension in the rope now? The correct answer was...
