    Where Am I Going Wrong in Calculating the Orbital Period?

    ((4(pi^2)(149.6 km^2))/t^2)/149.6 km=(6.67*10^-11(1.98*10^30 kg))/149.6 km^2 I do not understand what to do. If I cancel the 149.6 km from the denom. on the left side, I can't go much further.

    Where Am I Going Wrong in Calculating the Orbital Period?

    Homework Statement Calculate the Orbital Period for the following: Earth's orbit to the Sun. I get stuck towards the end. I must use Newton's second law and have the Universal Law of Gravitation equal the Centrifugal Force. Newton's gravitational constant: G= 6.67*10^-11 Nm^2/kg^2 Mass of...
