Question:

A Titan IV rocket has put your spacecraft in circular orbit around Earth at an altitude of 260 km. What is your orbital velocity? Give your answer in m/s.
This is the correct formula needed.

hint: the professor said the answer is between 7000 and 8500. i worked hours to trying to find something and nothing worked.

If you could kindly explain to me how you got to the answer i can work it out on my ti-83 so i can move onto similar problems on my homework. thank you!

2. to get the desired value, you must calculate it as if the entire expression is under the radical. syntax is ...

$\displaystyle \sqrt((6.673E{-11} * 5.594E24)/(3.395E6+2.6E6))$

you should get 8154.523297
