FIGURE 8-5 A 2.0-g bead slides along a wire, as shown in Figure 8-5. At point A, the bead is at rest. Neglect friction and use g = 10 m/s 2 .
-Refer to Figure 8-5. What is the kinetic energy of the bead at point B?

Question

FIGURE 8-5  A 2.0-g bead slides along a wire, as shown in Figure 8-5. At point A, the bead is at rest. Neglect friction and use g = 10 m/s 2 .
-Refer to Figure 8-5. What is the kinetic energy of the bead at point B?

Quizplus · Accepted Answer

Kinetic energy is given by KE = 1/2 mv^2. At point B, the bead has reached its maximum height and its velocity is zero. Therefore, its kinetic energy is also zero.
