Angular Frequency and Phase Difference problem 3


A pendulum is set into oscillation and a timer is turned on. After the time 9 s, we record 19 complete oscillations.

  • What is the frequency at which the pendulum oscillates?

  • How long does it take the pendulum to swing from one extreme position to the other?

  • What is the angular speed of the spendulum?
