Hello All :)

I am a student of mathematics, but I have only one semester of physics in college. I can't solve one with homework. Will there be anyone wise who can solve this?

The task is as follows:


Calculate: at what height the artificial satellite must move (orbit height): geostationary

determine the first and second cosmic velocities
