for angular speed it should be \[\omega =\theta \div time\]

Remember that radians are distance divided by the raidus.

Do you know how to convert all the units?

The radius will be \(24\) in.

yes and the rotaions would be 50mi/ 60mins

\[ \theta = \frac{x}{r}\\ \omega = \frac{v}{r} \]

which one og the formulas would be used here for angular speed i thought it was \[\theta \div time\]
anonymous

You aren't given any time here, so that formula is of no use.
