Question

What is the angular velocity of a 6-foot pendulum that takes 3 seconds to complete an arc of 14.13 feet?

Answer 1

But you can also use the other data using other formulas,
\[\Delta\theta=\frac{s}{R}=4.31/1.83=2.36\ rad\]
\[\omega=\frac{\Delta\theta}{\Delta t}=2.36/3=0.79\ rad/s\]

Answer 2

All measures in SI.
