## Homework Statement

How fast must a satellite 10,000 miles above Earth's surface travel, and how long does it take to complete one orbit of Earth?

## Homework Equations

[itex]v^2 = g*r[/itex]

## The Attempt at a Solution

10,000 miles + radius of Earth = 14,000mi =

[itex]v^2 = (9.8)(2.253*10^7m)[/itex]

v = 14859.13 m/s

The answer says 9400 miles per hour which is about 4202m/s.

Is there something I'm doing wrong or overlooking?
