FIGURE 8-3 A mass is attached to one end of a string. The other end of the string is attached to a rigid support. The mass is released at A and swings in a vertical arc to points B, C, and D, as shown in Figure 8-3. Neglect air resistance and use g = 10 m/ .
-Refer to Figure 8-3. At what point does the mass have the most kinetic energy?

Quizplus · Accepted Answer

The mass has the most kinetic energy at point C, which is typically the lowest point in a pendulum's swing or a similar system, where potential energy is minimized and kinetic energy is maximized.
