Part 1: A 25 kg box sits on a 20 degree incline ramp.

a) Calculate the parallel and perpendicular components of gravitational force acting on the box.

Part 2:

b) Starting with the simpler diagram, draw vectors representing all of the forces acting on the box.

Part 3:

c) The ramp has a 5 m height. If the box starts from the top at rest, what is its final velocity at the bottom after sliding down?
