The moon is 384,000 km from the earth and makes 1 revolution in 27.3 days. Find its angular and linear speeds in its orbit.
angular speed = 2 pi radians/27.3 days
linear speed = (orbit circumference)/(27.3 days)
They may want you to convert to radians and km per second. To do that, divide by the number of seconds in 27.3 days
