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)...
