Consider a 950-kg truck kept stationary by a light rope on a frictionless slope as shown in the figure. The rope forms an angle of 28° with the slope's surface, and the slope is angled at 20.0° relative to the horizontal. Determine the magnitude of the normal force exerted by the slope on the truck.

• B. 3.6 × 10³ N
• C. 7.1 × 10³ N
• D. 9.1 × 10³ N

Answer: (C)
