Well, just to get rid of the doubt.
Them, starting from the equation of position, and I found that the maximum values of the amplitude for the pendulum 1 occurs when:
επ(t/T) = nπ ---> t/T = n/ε
The time between maxima is T/ε, inversely proportional to the coupling spring constant...
Homework Statement
Two simple pendulums os equal length L=1m are connected with spring with a spring constant K=0,05 Mg/L. The pendulums are started by realeasing one of them from a displaced position. The subsequent motion is characterized by an oscillatory energy exchange between the...
