I mean circular velocity and escape velocity

Cosmic velocity - the initial velocity that must be given to any object to overcome the gravity of a celestial body due to its kinetic energy. The calculations are made assuming that there are no other celestial bodies and no resistance forces. I think we need to compare the centripetal force with the gravitational force of a satellite in orbit around Earth. Thus, the first space speed is about 8 km / s

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
