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
