A satellite is placed in orbit 100 km above the surface of the earth (radius = 6370 km, mass = 5.98 x 1024 kg).
If the satellite has a mass of 1500 kg, what is the force of gravity acting on it?

Now I did g relative to g earth for someone a few minutes ago
so g out there = 9.81*6370^2/6470^2)
= 9.51 m/s^2
Fg = 1500 * 9.51
Fg = 14364 Newtons
now before you ask
F = m a
F/m = a = 9.51 = v^2/r
so v^2 = 9.51 r
