The International Space Station (ISS) orbits the earth with a tangential velocity of 7.66 x 10^3 m/s, and the orbital radius of the ISS around the earth is 6.6 x 10^6 m. The mass of the ISS is 4.2 x 10^8 kg. a). What is the orbital period (s) of the ISS around the earth? b) Convert answer in a) to minutes. c). What is the net force acting on the ISS? (Hint: Use the centripetal Force Equation) d). Use Newton’s law of universal gravitation to estimate the mass of the earth using your answer from part(b) above.
