Determine the ratio of Earth's gravitational force exerted on an 80-kg person when at Earth's surface and when 1000 km above Earth's surface. The radius of Earth is 6370 km.
At a given point above the surface of Earth, the gravitational acceleration is equal to 7.3 m/s2. What is the altitude of this point, above the surface of Earth, in km.
Many satellites orbit Earth at maximum altitudes above Earth's surface of 1000 km or less. Geosynchronous satellites, however, orbit at an altitude of 35790 km above Earth's surface. How much more energy is required to launch a 415 kg satellite into a geosynchronous orbit than into an orbit 1000 km above the surface of Earth?
What is the Earth's gravitational force on you when you are standing on the Earth and when you are riding in the Space Shuttle 360 km above the Earth's surface? Answer as a fraction of the surface gravity of Earth. (The Earth's radius is 6400 km.)
1. A satellite 300 km above the surface of the Earth emits a radio wave pulse (wavelength = 25.0 m), Calculate the transit time for the wave to reach the surface of the Earth.
The space station orbits Earth about 400 km above the surface of Earth (NASA.gov). At this height the force of gravity from Earth is only about 10% less than on the surface of Earth. Using the concepts of circular motion and gravitational forces explain the following: 1. Why does the space station not fall down? 2. Why do the astronauts float inside the space station?
An asteroid is approaching earth at 1.48 km/s when it is 7500 km from earth's surface. How fast is it moving when it is 3100 km above earth's surface? Give answer in km/s.
please help me thank you!
