In the figure below, a horizontal force Fa of magnitude 24.0 N is applied to a 3.17 kg psychology book, as the book slides a distance d = 0.500 m up a frictionless ramp at angle 0 = 30.0. Psychology (a) During that displacement, what is the net work done on the book by Fa, the gravitational force on the book, and the normal force on the book? Work done on object by a constant forced is equal to the dot product of a force and the object's displacement. Work is also equal to the change in the kinetic energy. J m/s (b) If the book has zero kinetic energy at the start of the displacement, what is its speed at the end of the displacement?
