The speed to let the rocket enter the orbit is ...
vI = 7,91 km/s
vII = 11,19 km/s
vIII = 16,7 km/s
Depends on the weight of the rocket
And cosmic velocity - also referred to as the circular velocity, it is the speed that should be given to the body to enter into orbit around Earth. If a rocket launches from the surface of the earth, then it has to get at least 7.9 kilometers per second to get into orbit.
