. In the following figure, a horizontal force of magnitude 45.0 N is applied to a 4.00-
kg book as the book slides a distance d = 0.600 m up a frictionless ramp at angle θ
= 37.00
.
a) During the displacement, what is the net work done on the book by the
gravitational and the normal forces? [1]
b) If the book has zero kinetic energy at the start of the displacement, what is its
speed at the end of the displacement?
