This question is worth 25 marks. A block of stone, with a mass of 2600 kg, is being carried on a light sledge. It is held at rest on a smooth ramp by workers pulling on a rope attached to the block. The ramp makes an angle of 14° with the horizontal, and the rope is parallel to the ramp. Each worker can pull with a force of maximum magnitude 350 N. a.Draw a force diagram of the situation described....

By pulling a on rope attached to a crate of mass 77.0 kg, the crate is dragged across a floor. Let the coefficient of static friction between the crate and the floor be 0.830 and the angle between the rope and horizontal is 39.1 °. Find the minimum force required to move the crate. At a later time the crate is now dragged with this same force, and has already started moving, on a wet floor where the kinetic friction...

Block 1 (20 kg) is pulled by a rope from left to right up a ramp which is inclined 30 degrees from the horizontal. The rope pulls on block 1 with a force of 220 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.1. On a sheet of paper, draw the free body diagram for block 1 using the two-subscript notation from class. Assume that the x-axis...
