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 its highest speed?

Quizplus · Accepted Answer

The mass has its highest speed at the lowest point of its motion, which is typically where potential energy is minimized and kinetic energy is maximized. In many diagrams, this is represented by point C.
