Solved: Calculate the earths gravity force on a 75-kg
Chapter 13, Problem 13.15(choose chapter or problem)
Calculate the earths gravity force on a 75-kg astronaut who is repairing the Hubble Space Telescope 600 km above the earths surface, and then compare this value with his weight at the earths surface. In view of your result, explain why it is said that astronauts are weightless when they orbit the earth in a satellite such as a space shuttle. Is it because the gravitational pull of the earth is negligibly small?
