Hello, i was practicing for an exam and i found this problem on my book: A block of mass 3.00 kg is pushed up against a wall by a force P that makes a 50.0° angle with the horizontal as shown in the figure. The coefficient of static friction between the block and the wall is 0.244. a) Determine the possible values for the magnitude of P that allow the block to remain stationary b) Describe what happens if P is larger than Pmax. c) Describe what happens if P has a smaller value than Pmin. d) Repeat parts (a) and (b) assuming the force makes an angle of θ = 13.1° with the horizontal, and interpret your results. I dont understand a) and b) help is welcome!
