Question: Suppose the pendulum bob in Figure 8-29 has a mass of 0.33 kg and is moving to the right at point B with a speed

Suppose the pendulum bob in Figure 8-29 has a mass of 0.33 kg and is moving to the right at point B with a speed of 2.4 m/s. Air resistance is negligible.

(a) What is the change in the system's gravitational potential energy when the bob reaches point A?
(b) What is the speed of the bob at point A?
(c) If the mass of the bob is increased, does your answer to part (a) increase, decrease, or stay the same? Explain.
(d) If the mass of the bob is increased, does your answer to part (b) increase, decrease, or stay the same? Explain.
