A satellite with a mass of 290 kg moves in a circular orbit 3.00 107 m above the Earth's surface. What is the speed of the satellite if the force on the satellite is 87.4 N?

A satellite with a mass of 310 kg moves in a circular orbit 8.00 107 m above the Earth's surface.

(a) What is the gravitational force on the satellite?

Fg = [ (6.67x 10^-11) (310) (5.98 x 10^24) ] divided by

(8.00107m) ^2

Fg = you solved it. Fg = mv^2/r, radius 6400 miles?

(b) What is the speed of the satellite? in km/s

v = sqrt (2gh)

v = you solved it.

(c) What is the period of the satellite? in h

t = 2d / g.

t = you solve it.
