A satellite in a circular orbit 879.4 mi above the earth makes one complete orbit every 83.42min. What is its linear velocity? Use 3963 mi for the length of the radius of the earth.

  • Math -

    the radius of your satellite's orbit is 3963+879.4 = 4842.4

    C = 2pi*r = 30425 mi

    velocity = 30425mi/83.42min = 364.73mi/min
