    Using Kepler's constant for Jupiter

    ok, I'll try that. thanks a bunch for the help. I'll come back to this topic again next week as I'm going on a short trip.

    Using Kepler's constant for Jupiter

    Thanks for the reply. according to what you said, in this case, would it be better to use the formula with G in it? also, Should the calculation be done in years or days?

    Using Kepler's constant for Jupiter

    Homework Statement Given that Jupiter has a mass of 1.9*10^27kg, and the sun has a mass of 1.99*10^30kg: a)Calculate the value of Kepler's constant for JupiterHomework Equations k = r^3/T^2 K = G(M+m)/4pi^2The Attempt at a Solution Well since the question only gave me the mass of Jupiter and...

    Magnitude of force of box on ramp.

    So for part b.) Fnet would equal to zero? if so would the equation go about like this?: Fnet = Fg_y cos45 - U_sFn cos 45 + F_app ? Fg_y = force of gravity in the y direction U_s = coefficient of static friction Fn = normal force U_sFn = force of static friction (Fs)or would i have to instead...

    How Do You Calculate Forces on a Banked Curve with Friction for a Race Car?

    perhaps this may work? Us = Fc/Fn Fn = mg = 1450kg*9.8m/s^2 = 14210N Us = 3808N/14210N = 0.267?
