- A force of 12.0 N acts on a 4.6 kg object through a parallel distance of 1.6 m. How much work is done on the object? Your Answer:A box with with a mass m = 2kg is being pushed up a ramp by an unknown pushing force Fp. The coefficient of static friction between the box and interface is 0.7. The coefficient of kinetic friction between the box and interface is 0.6. The incline of the ramp is 15 degrees. The velocity of the box is constant. The surface of the ramp is 12 m. What is the work done by normal force while the box is being pushed the entire length of the ramp? [ I think that it is 0 N, since the x component of normal force which is parallel to motion is 0. Is that correct?]A 2.28 kg block is pushed 1.69 m up a ver- tical wall with constant speed by a constant force of magnitude F applied at an angle of 60.8° with the horizontal.

- The mover in problem 13 uses a ramp, which makes the task easier by requiring a smaller force to raise the crate to the truck bed. This force must be exerted over a greater distance, so the work done should be the same. In reality, because of the frictional force between the crate and the ramp, the work required is greater than that needed to lift the crate directly onto the truck. The mover does 4365 J of work sliding the crate up the ramp. The force the mover exerts on the crate is 1302 N. How long is the ramp?A chain is held on a frictionless table with one fourth hanging over the edge.
