1. Say you are on the surface of Mars with the surface gravity of Earth (take Earths surface gravity as 9.8 m/s). Take the radius of Mars as 3400 km. Now, say you takeoff like Superman but with a jetpack and orbit around Mars at its surface. Just take r-Rmans and assume Mars is a perfectly smooth sphere. (a) What is your orbital speed at the surface of Mars? (b) What is the period of this orbit? (period -time to go around once) (c) Now you want to takeoff and escape to infinity. What is the minimum escape speed required to completely escape the gravity of Mars? (Dont just Google it. Derive your answer from first principles.)
