A man pushes on a piano with mass 180 kg; it slides at constant
velocity down a ramp that is inclined at 19.0 above the horizontal
floor. Neglect any friction acting on the piano. Calculate the magnitude
of the force applied by the man if he pushes (a) parallel to the incline
and (b) parallel to the floor.

Problem 1: While training on the planet Dagobah, Luke Skywalker is asked by Yoda to hold a block with a mass of 6.80kg against a vertical wall using only the Force. Luke applies the Force with a magnitude of 115.0N at an angle of 52.0° with respect to the horizontal. Luke discovers that if the Force increases any more, the block begins to slide up the wall. What is the coefficient of static friction between the block and the wall? Assume that gravity on Dagobah is the same as gravity on Earth.
