1. The problem statement, all variables and given/known data A pendulum has a period of 5seconds. It is damped so that the amplitude falls to one half its original value in 100seconds. What is the Q? I am having trouble relating the Q with the information I have. Period = 5 seconds There are 5 periods ω = 2π/5 Please help! Thanks XD 2. Relevant equations 3. The attempt at a solution I tried getting the total Energy E= T+V but then I have no idea what to do with that to get the Q.
