Find the frequency of oscillation when a meterstick is hung as a compound pendulum with the pivot at its 90-cm mark. Repeat for the pivot at the 50.1-cm mark.

A 0.7-kg mass at the end of a spring oscillates 10 times per second with an amplitude of 0.9 m. Determine its speed (in m/s) when it passes the equilibrium point. (what equation can I use to find the speed of the equalibrium point?)

What if we wanted to use a conical pendulum to tell time? It would be great if we had a pendulum that made one revolution every hour. How long of a pendulum, though, would we need for this if the angle of the pendulum was a mere 2.00° from the vertical?

The mass on the end of a pendulum is 0.04 kg and hangs from a string of length 1.2 m. The pendulum is raised to point Q, which is 0.10 m above its lowest position, and released so that it oscillates between the points P and Q as shown below. Describe one modification that could be made to double the period of oscillation.
