A satellite moves in a circular orbit around Earth at a speed of 4390 m/s
(a) Determine the satellite's altitude above the surface of Earth.(meters)
(b) Determine the period of the satellite's orbit.
(hours)
I used the equation M(sattelite)V^2/r = M(sattelite)(Mass(earth)G/r^2
and tried to solve for r by canceling out one r and the M(sattelite) which gave me
r = GM(earth)/v^2
the answer i keep getting is 20,592,718.12m
but it is not right....
