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: MALL * 7 kg , mcHAIN * 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= 4s. 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?

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 =7 kg , P1: MCHAIN 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 Tz 4s. 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?
