A satellite has a mass of 106 kg and is located at 1.96 106 m above the surface of Earth.
(a) What is the potential energy associated with the satellite at this location?
J

(b) What is the magnitude of the gravitational force on the satellite?
N

  • physics -

    a) Gravitational potential energy = mgh
    = (106kg)(10m/2^2)(1.96106m)
    = 2078.7236 J

    b) F = ma
    = (10kg)(10 m/s^2)
    = 100 N
