Question

The Moon orbits the Earth every `27.3` days. Determine the angular velocity in degrees. Help?

Answer 1

`v_(ang)=(360^o)/("2,358,720 s")=1.53xx10^-4` degrees per second

Explanation:

The moon travels a full circle (technically very slightly elliptical but we can ignore that) of `360^o` in `27.3` days.

We need to convert the time period into the SI unit, the second.

`t = "27.3 days" xx "24 hours"/"day" xx "60 minutes"/"hour" xx "60 seconds"/"minute" = "2,358,720 s"`
