1. The problem statement, all variables and given/known data You are working on a project with NASA to launch a rocket to Mars, with the rocket blasting off from earth when earth and Mars are just aligned along a straight line from the sun. As a first step in doing the calculation, assume circular orbits for both planets. If Mars is now 64.7 degrees ahead of the earth in its orbit around the sun, when should you launch the rocket? Give your answer in days to the nearest whole number (i.e. 45.6 = 46) Note: For this problem you need to know the fact that all the planets orbit the sun in the same direction, and the year on Mars is 1.88 earth years. 2. Relevant equations The rotational kinematics equations, but I can't seem to figure out which one to use. If you don't have them handy, here's a link: http://bama.ua.edu/~jharrell/PH105-S03/exercises/rot_mot_eqs.htm [Broken] Sorry, I don't know how to retype those on here. 3. The attempt at a solution I honestly don't know where to start. I had a few ideas but none of them came close. The answer is 140 days. Any help is appreciated.
