FIGURE 7-2 Three Applied Forces, F₁ = 20

question 22

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 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
