Chapter 5, Problem 66(choose chapter or problem)
A block of mass 3.00 kg is pushed up against a wall by a force P S that makes an angle of u 5 50.0 with the horizontal as shown in Figure P5.66. The coefficient of static friction between the block and the wall is 0.250. (a) Determine the possible values for the magnitude of P S that allow the block to remain stationary. (b) Describe what happens if 0 P S 0 has a larger value and what happens if it is smaller. (c) Repeat parts (a) and (b), assuming the force makes an angle of u 5 13.0 with the horizontal
