A 10 m ramp with a mass of 5.0 kg rests against a wall. The end of the ramp touches the wall at a height (h) of 1.5 m. The center of gravity for the ramp is halfway up the ramp. A crate with a mass of 10.0 kg rests halfway up the ramp. What forces are exerted on the ramp by the wall and by the ground, assuming that the wall is frictionless but the ground is not? My teacher said we could pick any angle so im choosing a 40 degree angle.
