In a grandfather clock, the second hand moves forward by one second for each half period of the clock’s pendulum. a. How long would you expect the pendulum to be in a grandfather clock? b. If you took a grandfather clock to the moon, where gravity is 1/6 Earth’s gravity, what would you expect to happen to the period of the clock? c. What happens to the apparent passage of time on the moon?
The sweeping second hand on your wall clock is 16 cm long. Assume the second hand moves smoothly. A) What is the rotational speed of the second hand? Express your answer in radians per second to two significant figures. B) Find the translational speed of the tip of the second hand. Express your answer with the appropriate units. C) Find the rotational acceleration of the second hand. Express your answer in radians per second squared.
