A pendulum of length l is mounted in a rocket. (Use the following as necessary: l and g. Enter only the word ?none? if the pendulum does not oscillate.)
(a) What is the pendulum?s period if the rocket is at rest on its launch pad?
(b) What is its period if the rocket is accelerating upward with acceleration a = 4/7 g?
(c) What is its period if the rocket is accelerating downward with acceleration a = 4/7 g?
(d) What is its period if the rocket is in free fall?
