Q4]
You want to use a pendulum clock on the moon (gm = 1.625).
a) What length should the pendulum have in order for it to have a period of T = 1.00s? [6pt.]
b) Now you need a clock for your trip into interstellar space. A pendulum clock won't work, even while
moving with a constant velocity. Why? [3pt.]
c) You then decide to create a clock from a spring and an object with a mass m = 655g. What is the
amplitude of the spring if it has a maximum velocity of Vmaz = 0.5m, and a period of T = 1.00s?
[8pt.]
