- You need to set up another simple ramp using the board from Part A (i.e., a board of length 1.56 mm ). (Figure 5) If the ramp must be at a 25∘∘ angle above the ground, how far back from the bed of the truck should the board touch the ground? Assume this is a different truck than the one from Part A. Express your answer in meters to three significant figures.1. The setup shown by the diagram below was used to calculate the force experienced by a small mass m situated at a distance r from the geometric center of a spherical shell with mass M, radius R, and a wall thickness of t.
