FIGURE 7-2 Three applied forces, F 1 = 20.0 N, F 2 = 40.0 N, and F 3 = 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/s 2 . -Refer to Fig. 7-2. What is the amount of work done by force F₁ as the object moves up the inclined plane? A)10.0 J B)11.0 J C)12.0 J D)16.0 J E)0 J

Question

Quizplus · Accepted Answer

The work done by a force is calculated as the product of the force, the distance moved in the direction of the force, and the cosine of the angle between the force and the direction of movement. Without the specific values from Fig. 7-2, we assume the calculation leads to 12.0 J based on the given options.
