A pendulum requires 2 seconds to complete a cycle, which consists of a complete back-and-forth oscillation (extreme point to equilibrium to opposite extreme point back to equilibrium and finally to the original extreme point). As long as the amplitude of the motion (the amplitude is the distance from the equilibrium position to the extreme point) is small compared to the length of the pendulum, the time required for a cycle is independent of the amplitude.

• How long does it take to get from one extreme point to the other, how long from an extreme point to equilibrium, and how long to go from extreme point to equilibrium to opposite extreme point and back to equilibrium?

answer/question/discussion: ->->->->->->->->->->->-> :

It takes 2 seconds to go from one extreme to the other ( one complete cycle ). It takes half that, 1 second, to go from one extreme point to equilibrium. And it takes 3 seconds to go from extreme point to equilibrium to opposite extreme point.

• What reasonable assumption did you make to arrive at your answers?

It took me 5-7 minutes to arrive at my answers.
