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/s 2 .
-Refer to Figure 8-9. What is the kinetic energy of the object at the bottom of the inclined plane?

Quizplus · Accepted Answer

The kinetic energy at the bottom of the inclined plane is equal to the initial potential energy at the top, assuming no energy is lost to friction or air resistance. If the potential energy at the top was 800 J, then the kinetic energy at the bottom would also be 800 J.
