The weight w of an object varied inversely as the square of the distance d between the object and the center of Earth. If a man weighs 90 kg on the surface of Earth, how much would he weigh 400 km above the Earth's surface? (Given: The radius of the Earth is approximately 6400 km.)
the weight, w, of an object varies inversely as the square of the distance, d, between the object and the center of Earth. If a man weighs 75kg on the surface of Earth, how much would he weigh 300km above the Earth's surface? (given the radius of the earth is approximately 6400km)
If G = 6.674 ⨉ 10 −11m3/kg/s 2and M Earth= 5.972 ⨉ 10 24kg and the sidereal period of the Earth is 27.32 days, then, from Kepler’s third law in #4, what is the expected orbital distance of the Moon?
