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 speed of the object at the bottom of the inclined plane?

Quizplus · Accepted Answer

The speed of the object at the bottom of the inclined plane is calculated using energy conservation principles, assuming no friction. The potential energy at the top is converted to kinetic energy at the bottom, resulting in a speed of 12.6 m/s.
