A Martian civilization is attempting to develp the capabilities for space travel. They have built a prototype satellite with a mass of 578kg that they plan to put in orbit Mars a distance of 602km above the surface of mars.(adsbygoogle = window.adsbygoogle || []).push({});

A) Using the data provided, calculate the orbital velocity of the satellite.

B)Find the period of the satellite.

C)How would you answer to (a) change if the satellite was twice as massive? Explain how you know.

D) How would you answer to (a) change if the satellite was to be twice as far from the surface of Mars?

Please explain thoroughly. I really don't understand any of this stuff and need help studying.

The attempt at a solution

I could only do part A and I used the square root of Gm/r which equals

the square root of (6.67E-11)*(6.42E23)/3398km which equals 3398000m and my answer was 3549.921453 m/s

Everything else I'm soooo lost and going to cry bc I don't understand
