The International Space Station (ISS) is orbiting in a nearly circular orbit about the Earth at 413 km from the surface of the Earth. Its mass equal 450000 kg. 1. What is, in km/h, the orbital speed of the ISS? 2. What is, in minuts, its orbital period? Knowing that: the universal gravitational constant has a value of 6.674 10-1 [m/(kg s)], the Earth has a radius of 6371 km and a mass of mEarth = 5.972 x 1024 kg.
