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
