A crate of mass m1 = 15.3 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 1.4 m, starting from rest. Find the work done by gravity on the sliding crate.
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 1.70 m, starting from rest. If the frictional force on the sliding crate has magnitude 21.5 N and the tension in the rope is 121.5 N, find the total work done on the sliding crate.
The total work done on the sliding crate is
