Yeah it is but I am assuming I am supposed to use what the question gives me.. let me redo the calculation with 1738km's though...
Alright so I get to the part where you have to square root T^2 and I get 0.21649... days (I think) and if I multiply that by 24, I should get hours, but when I do...
Homework Statement
On each of the apollo missions the command module was placed in a very low aprox circular orbit above the moon. Assum the avrg hieght was 60km above surface of moon and moons radius is 7738km. (Mass of moon=7.34x10^22kg)
What was the command modules orbital period...
