24 O In Fig. 7-33, a horizontal force F, of magnitude 20.0 N is applied to a 3.00 kg psychology book as the book slides a distance d = 0.500 m up a fric- tionless ramp at angle e= 30.0°. (a) During the displacement, what is the net work done on the book by F, the gravi- tational force on the book, and the nor- Pachoy mal force on the book? (b) If the book has zero kinetic energy at the start of the displacement, what is its speed at the end of the displacement? Figure 7-33 Problem 24.

69. An external force moves a 3.50-kg box at a constant speed up a frictionless ramp (Figure 6-46). The force acts in a direction parallel to the ramp. (a) Calculate the work done on the box by this force as it is pushed up the 5.00-m ramp to a height of 3.00 m. (b) Compare the value with the change in gravitational potential energy that the box undergoes as it rises to its final height. Example 6-10 5.00 m F V 3.50 kg Figure 6-46 Problem 69 T 3.00 m
