## Homework Statement

Gravity causes a centripetal force that allows satellites to travel around planets.

How fast must a 102-kg satellite travel to maintain a circular orbit 352 km above Earth's surface?

## Homework Equations

F=m(v^2/r) -----> (F/m) x r= v^2, then square root

F= force

m=mass

v=velocity

r=radius

## The Attempt at a Solution

So basically, I'm solving for v in km/s.

The mass is 102 kg

For radius, I added the radius of the Earth in meters with the circular orbit of 352 km.

6371000m + 352000m= 3723000m which is r.

The problem is that I need to solve for F. Does anyone know how to continue with this problem?
