Question

A flagpole is a harmonic oscillator, flexing back and forth with a steady period. If you want to increase the amplitude of the pole's oscillation as much as possible by pushing near its base, when should you push?

Answer 1

You should push on it as it flexes away from you

Step-by-step explanation:

Amplitude is the greatest displacement of an oscillating object. So to increase the amplitude of the pole's oscillation as much as possible you need to push on it as it flexes away from you.
