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 Figure P5.53. The coefficient of static friction
between the block and the wall is 0.250. Determine the
possible values for the magnitude of P that allow the
block to remain stationary.

the stationary horizontal tabletop. The block of mass m is
placed near the bottom of the incline and is released with a
quick push that sets it sliding upward. The block stops near
the top of the incline as shown in the figure and then slides
down again, always without friction. Find the force that the
tabletop exerts on the incline throughout this motion in
terms of m, M, g, and 0.
