URGENT//Period and frequency question 1. The problem statement, all variables and given/known data 1) An adult and a child are sitting on adjacent identical swings. Once they get moving, the adult, by comparison to the child, will necessarily swing with a) a much greater period b) a much greater frequency c) the same period d) the same amplitude 2. Relevant equations T= 2pi(square root of m/k) 3. The attempt at a solution THe answer is a B... Can anyone explain why?? I think it's an A b/c as m increases, the T increases??!
