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.

Explanation
Since energy is conserved and nonconservative forces do no work,
mechanical energy is conserved. Let the y-axis point
straight upward....
A block (m1 = 3.7 kg) is being pulled up a ramp (at an angle = 36.4 degrees from the horizontal) with a cable that is parallel to the ramp's surface. The cable runs over a pulley that is at the top of the ramp and then is attached to a hanging block (m2 = 17 kg). What is the tension in the cable? Assume that the coefficient of kinetic friction for the block on the ramp is 0.2.
mi m2 Two wooden crates rest on top of one another. The smaller top crate has a mass of my = 24 kg and the larger bottom crate has a mass of m2 = 87 kg. There is NO friction between the crate and the floor, but the coefficient of static friction between the two crates is Hs = 0.82 and the coefficient of kinetic friction between the two crates is Mk = 0.64. A massless rope is attached to...
Mass M1 = 4 kilograms is suspended on a massless frictionless
pulley and is connected with a massless rope to Mt = 2 kg, a mass

A mass m1 = 3.4 kg rests on a frictionless table and connected by a massless string over a massless pulley to another mass m2 = 4.7 kg which hangs freely from the string. When released, the hanging mass falls a distance d = 0.7 m. How much work is done by the normal force on m1? What is the final speed of the two blocks? What is the tension in the string as the block falls? The work done...

Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1=13.75 kg is on a horizontal table and the other block with mass m2=6.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. Part (a) Assuming friction forces are negligible, write an expression, using only the variables provided, for the acceleration that the block of mass...
