1.Nasa fires a 1 tonne space probe, from a stable orbit of altitude 13,620km using a giant rail gun. The rail gun provides the probe with 9.97165*10^10 J of additional kinetic energy. Determine if the probe has enough velocity to escape the Earth's gravity well. The Earth's mass and radius are 5.98*10^24kg and 6380km respectively.
