Homework Statement

The space shuttle is in a 310 mile high orbit. What are the shuttle's orbital period, in minutes, and its speed?

Homework Equations

Period = 2(pi)r/v

The Attempt at a Solution

I can't figure out how to find the period without already having the velocity.

Hi Lynn311, welcome to PF.

There is an expression giving the speed of a satellite at a given distance from the center of the Earth. If you don't remember it, look it up.
