At the end of the semester, you are loading your gear into a van to go
home. In loading the van, you can either lift a 44.47 kg crate straight up
(method 1) or push it up a 2.61 m long ramp that is inclined at an angle
above the horizontal (method 2). In both methods, the crate is moved at a
constant speed,, and the vertical distance from the ground to the floor of
the van has the same value h (see the drawing). In method 1, no friction is
present. In method 2, however, a frictional force does -488.15 J of work
on the crate. In applying your nonconserved pushing force to the crate,
you do twice as much work in method 2 as in method 1. Find the angle X.
