Part A 

1 mile = 1609 m

Orbital speed, v,

v=G·MR

Height of orbit, H = 230 miles (1609 m / 1 mile) = 0.37 × 106 m

Radius of the Earth, R = 6.37 × 10m

Radius of the orbit, r = R + H = 6.37 × 106 + 0.37 × 106 = 6.74 × 106 m

Mass, m = 5.98 × 1024 kg

Gravitation constant, G = 6.673 × 10-11 N.m2 / kg2
