## Homework Statement

What is the orbiting speed (m/s) of a satelite orbiting Earth in a circular path 1000 km above Earth's surface? (Use 4 sig figs)

## Homework Equations

universal constant of 6.67E-11

r of Earth 6.37E6 m (given by teacher)

mass of earth 6E24 kg (given by teacher)

derived v=sqrt(G*M/r)

this is what i have read will solve this equation for me

## The Attempt at a Solution

First I converted the 1000 km above earth to m and added that and the radiace of Earth together to get 7.67E6 m (r) then I solved for v: sqrt(6.67E-11*6E24/7.37E6)=7369 m/s

what am I doing wrong? There is also a possiblity that the teacher is wrong, its happened before on his website
