FIGURE 8-4
-A 2.0 g bead slides along a wire, as shown in Fig. 8-4. At point A, the bead is at rest. Neglect friction.
(a) What is the potential energy of the bead at point A?
(b) What is the kinetic energy of the bead at point B?
(c) What is the speed of the bead at point B?
(d) What is the speed of the bead at point C?
