Multiple Choice
FIGURE 7-2 Three applied forces, F1 = 20.0 N, F2 = 40.0 N, and F3 = 10.0 N act on an object with a mass of 2.00 kg which can move along an inclined plane as shown in the figure. The questions refer to the instant when the object has moved 0.600 m along the surface of the inclined plane in the upward direction. Neglect friction and use g = 10.0 m/s2.
-Refer to Fig. 7-2. What is the amount of work done by force F2 as the object moves up the inclined plane?
A) 0 J
B) 12.0 J
C) 16.0 J
D) 24.0 J
E) 20.8 J
