FIGURE 8-4 An object of mass 2 kg is held at the top of a triangular wedge as shown in Figure 8-4, and then released. The reference level for potential energy is at the base of the triangle. Neglect friction and use g = 10 m/s 2 .
-Refer to Figure 8-4. What is the kinetic energy of the object at the top of the wedge?

FIGURE 8-4  An object of mass 2 kg is held at the top of a triangular wedge as shown in Figure 8-4, and then released. The reference level for potential energy is at the base of the triangle. Neglect friction and use g = 10 m/s 2 .
-Refer to Figure 8-4. What is the kinetic energy of the object at the top of the wedge?

Quizplus · Accepted Answer

At the top of the wedge, the object has only potential energy and no kinetic energy since it has not yet been released. Therefore, the kinetic energy at the top of the wedge is 0 J.
