    a) Determine the speed Vo needed by the ISS to maintain orbit.

    Vo^2/((3.72+0.35)*10^6) = Me*G / (((3.72+0.35)*10^6)^2

    Me*G = 4*10^14 m^3/sec^2Vo^2*((3.72+0.35)*10^6) = 4*10^14

    Vo = √ 4*10^14 / ((3.72+0.35)*10^6)  = 9,914 m/sec  (9910 with 3 sign. digits)

    b) Determine the orbital period T of the ISS in minutes.

    T = 2PI*((3.72+0.35)*10^6) / (Vo*60) = 6.2832*4.07*10^6/(9914*60) = 43.0 min
