Gravity and orbit

  1. Mar 27, 2010 #1
    Tom and Jerry decide to go space travel. They are in a spaceship travelling in a circular orbit completing one revolution in 12 hrs (43200seconds)

    a. Calculate speed of the spaceship relative to the centre of the Earth
    b. Calculate Tom's weight while he is in orbit around the Earth.
