Planet Ukbar has the mass 6e+22 kg and radius 4000000 m. You are planning an orbiter to be on a circular orbit around Ukbar. If the radius of this orbit to be 70000000 m,

The speed of the orbiter should be-------- m/s

The period of the orbiter will be ---------- h

In order to start returning home, what speed will the orbiter have to reach to escape Ukbars orbit?

--------- m/s
