1. The problem statement, all variables and given/known data I calculated [tex]T_o[/tex] to be 1.27 seconds and [tex]"T_o"'[/tex] to be 1.23 seconds, each representing a normal mode of oscillation. These are correct according to the text. Here is the question: what is the time interval between successive maximum possible amplitudes of one pendulum after one pendulum is drawn aside and released? (answer: 40 seconds) 3. The attempt at a solution I'm not even quite sure how to begin this problem, or what it is asking precisely. Is this suggesting that both modes of oscillation are superimposed? If this is the case, the superimposed period would be 1.25s.... where am I going wrong here?
