A pendulum-driven grandfather clock often has a small mass that can be slid up and down the pendulum arm to adjust the swing period in case the clock runs to0 fast or too slow. If one particular clock is losing one second every week, what should be done, and why? (a) Move the mass up, because the lower rotational inertia will make the clock run faster. (b) Move the mass up, because the higher rotational inertia will make the clock run slower. (c) Move the mass down, because the lower rotational inertia will make the clock run faster. (d) Move the mass down, because the higher rotational inertia will make the clock run slower. 3.

Consider two cylinders that start down identical inclines from rest except that one is frictionless. Thus one cylinder rolls without slipping, while the other slides frictionlessly without rolling. They both travel a sh01t distance at the bottom and then start up another incline. (a) Show that they both reach the same height on the other incline, and that this height is equal to their original height. (b) Find the ratio of the time the rolling cylinder takes to reach the height on the second incline to the time the sliding cylinder takes to reach the height on the second incline. (c) Explain why the time for the rolling motion is greater than that for the sliding motion.
