This time we have a crate of mass 38.7 kg on an inclined surface, with a coefficient of kinetic friction 0.249. Instead of pushing on the crate, you let it slide down due to gravity. What must the angle of the incline be, in order for the crate to slide with an acceleration of 7.86 m/s^2?

A construction worker pushes on a 10 kg crate down an inclined plane that is 7.0 m long and is inclined at an angle of 20 degrees to the horizontal. As a result, the crate slides down the entire length of the plane with a constant speed of 3.0 m/s. Suppose that the worker pushes directly on the crate in a direction parallel to the incline with a force of 50 N for the entire length of the plane. A)...
