Homework Help: Orbital Period and Velocity Question

  1. Oct 8, 2009 #1
    1. The problem statement, all variables and given/known data
    The space shuttle is in a 310 mile high orbit. What are the shuttle's orbital period, in minutes, and its speed?

    2. Relevant equations
    Period = 2(pi)r/v

    3. 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.
