Question

A block of mass 3.00 kg is pushed up against a wall by a force PS that makes an angle of u5 50.0° with the horizontal as shown in Figure P5.34. The coefficient of static friction between the block and the wall is 0.250. (a) Determine the possible values for the magnitude ofPS that allow the block to remain stationary. (b) Describe what happens ifuPSuhas a larger value and what hap-pens if it is smaller. (c) Repeat parts (a) and (b), assuming the force makes an angle of u5 13.0° with the horizontal.
