Homework Help: Satelitle Problem

  1. Sep 22, 2009 #1
    1. The problem statement, all variables and given/known data

    The astronaut orbiting the Earth in Figure P4.32 is preparing to dock with a Westar VI satellite. The satellite is in a circular orbit 600 km above the Earth's surface, where the free-fall acceleration is 8.18 m/s2. Take the radius of the Earth as 6400 km.

    a.) Determine the speed of the satellite.

    b.) Determine the time interval required to complete one orbit around the Earth.

    2. Relevant equations

    centripetal(radial) acceleration= v^(2) / r

    v= 2(pi)r/ T

    3. The attempt at a solution

    8.18 m/s^(2) * 600,000m= v^(2)

    v= 2215.401 m/s

    Is that right?
