A crate of weight Fg is pushed by a force P on a horizontal floor. (a) If the coefficient of static friction is μs and P is directed at an angle below the horizontal, show that the minimum value of P that will move the crate is given with: P=μs F g sec(theta)/(1-μstan(theta)), (b) discover the minimum value of P that can produce motion when μs=0.4, Fg=100N, and theta=0,15,30,45,60 degrees.
