Asked by Andrea
A swing is 2m long. how often do you need to push it to increase its swing's amplitude the most?
L=2m
When amplitude is the most KE=0 and PE is at its maximum. But i'm not completely sure how to solve this problem.

I am sure you have pushed a swing.
You push it once a period.
In other words every T seconds.
T = 2 pi sqrt(L/g)
= 2 pi sqrt (2/9.8)
