Orbital speed & time required

wowdusk

1. The problem statement, all variables and given/known data
the solar maximum mission satellite was placed in a circular orbit about 150 miles above earth. Determine (a) the orbital speed of the satellite and (b) the time required for 1 complete revolution


2. Relevant equations



3. The attempt at a solution

3.211k

But you haven't shown an attempt yet! Here's where I would start:

The force of gravity between the satellite and the earth provides the centripetal force.
Fg = Fc
What should we do from here?

try thinking about newtons laws of motion and applying one of them in particular radially =]
