B) Yes, energy is being converted between potential and kinetic but the total momentum remains 7. Is the momentum of a pendulum while it swings from one extreme to its opposite extreme a conserved? A) Yes, the momentum is zero at both extremes. constant. C) No, as energy is converted between potential and kinetic the total momentum changes. D) No, the impulse at any moment is zero. 8. In order to treat a pendulum consisting of a gulf ball on a string as a simple harmoe oscillator some assumptions must be made. Which of the following statements is N0T assumed? A) The mass of the gulf ball is negligible. B) The mass of the string is negligible. C) Air resistance is negligible. D) The change in vertical height is negligible. 9. This question has two correct answers. Both must be answered correctly to earn credit. On the Earth a mass is attached to a vertical spring. The mass is held upwards so that the spring is unstretched and then released. Another mass is attached to a string to make a pendulum. The pendulum is pulled over 10° and released. If the spring oscillator and the pendulum were taking to the Moon and set in motion in the same way as before, which of the following would change? A) The spring oscillator's period.
