A box with a mass of 10 kg is pushed with a constant force of 100 N a distance of 3.0 m up a ramp that makes an angle of 30 from the horizontal. The coefficient of kinetic friction between the box and the ramp is 0.35.

a. Compute the work done by each of the four forces acting on the box.

b. Assuming the box starts at rest, determine the speed of the box at it reaches a distance of 3.0 m.
