A block of mass m = 18.5 kg rests on an inclined plane with a coefficient of static friction of μs =
0.075 between the block and the plane. The inclined plane is L = 6.5 m long, and it has a height
of h = 3.85 m at its tallest point.
Part (a) What angle, θ in degrees, does the plane make with respect to the horizontal?
Part (b) What is the magnitude of the normal force, FN in newtons, that acts on the block?
Part (c) What is the component of the force of gravity along the plane, Fgx in newtons?
