66. A block of mass 3.00 kg is pushed up against a wall by a force P that makes an angle of 0 = 50.0° with the horizontal as shown in Figure P5.66. The coefficient of static fric- tion between the block and the wall is 0.250. (a) Determine the possible values for the magnitude of P that allow the block to remain station- P Ꮎ Figure P5.66 ary. (b) Describe what happens if | P | has a larger valu and what happens if it is smaller. (c) Repeat parts (a) anc (b), assuming the force makes an angle of 0 = 13.0° with the horizontal.
