question 77

Multiple Choice

FIGURE 8-9 An object with a mass of 10.0 kg is at rest at the top of a frictionless inclined plane of height 8.00 m and an angle of inclination 30.0° with the horizontal. The object is released from this position and it stops at a distance d from the bottom of the inclined plane along a horizontal surface, as shown in Figure 8-9. The coefficient of kinetic friction for the horizontal surface is 0.400 and g = 10.0 m/s².
-Refer to Figure 8-9. What is the kinetic energy of the object at the bottom of the inclined plane?

• A) 400 J
• B) 500 J
• C) 700 J
• D) 800 J
• E) 900 J
