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: m(BALL) = 7 kg , m(CHAIN) = 0.5 kg , and l(CHAIN) = 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 = 4 s . What is the acceleration due to gravity on this planet? (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?

Question
  1. 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: m(BALL) = 7 kg ,

    m(CHAIN) = 0.5 kg , and l(CHAIN) = 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 = 4 s . What is the acceleration due to gravity on this planet?
    (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?
