**1. Homework Statement**

What is the total mechanical energy of a 290 kg satellite in a geosynchronous orbit around the Earth?

**2. Homework Equations**

W= K + U

_{G}where K= 1/2 (mv

^{2}) and U

_{G}= -(GmM)/r

F

_{c}= ma

_{c}where a

_{c}= v

^{2}/r

**3. The Attempt at a Solution**

I think the geosynchronous part is what is throwing me off. What would the radius be so I can solve for the initial speed.
