Question

You are abducted by aliens and find yourself locked in a large room on some strange
planet. To pass the time, you decide to do some experiments using a ball-and-chain that
you find on the floor. You make the following estimates:
mBALL approximately equals 7 kg, mCHAIN approximately equals 0.5 kg, and  CHAIN approximately equals 2 m.

(a) When you hold the free end of the chain above your head and allow the ball to swing
like a pendulum, you use your wristwatch to measure the period as T approximately equals 4s. What is the
acceleration due to gravity on this planet? Give explanation to your answer

(b)If the ball accidentally hits a wall, how long does it take for this jolt in the chain to
travel up to your hand?
