What Is The Speed Of A Satellite Orbiting At That Height

Assume rearth 6 37 106 m.

What is the speed of a satellite orbiting at that height.

R orbital radius earth s equatorial radius height of the satellite above the earth surface r 6 378 km 35 780 km r 42 158 km r 4 2158 x 107 m speed of the satellite is 3 0754 x 103 m s. This converts to about 16 800 miles per hour. Determine the speed acceleration and orbital period of the satellite. At an altitude of 124 miles 200 kilometers the required orbital velocity is a little more than 17 000 mph about 27 400 kph.

Speed orbital period specific orbital energy. Objects in leo encounter atmospheric drag from gases in the thermosphere approximately 80 500 km above the surface or exosphere approximately 500 km or 311 mi and up depending on orbit height. An earth orbiting satellite s motion is mostly controlled by earth s gravity. 465 1 m s 1 674 km h or 1 040 mph 23 h 56 min 62 6 mj kg.

To maintain an orbit that is 22 223 miles 35 786 kilometers above earth the satellite must orbit at a speed of about 7 000 mph 11 300 kph. An artificial satellite is revolving around the earth in circular orbit at a height of 1000 km at a speed of 7364 m s. The nearer to earth the faster the required orbital velocity. What s the speed of such a satellite.

Solution for at what height above the earth is the acceleration due to gravity 25 0 of its value at the surface. Orbiting at earth s surface equator theoretical 6 378 km. What is the speed of a satellite orbiting at. A satellite wishes to orbit the earth at a height of 100 km approximately 60 miles above the surface of the earth.

The height of the orbit or distance between the satellite and earth s surface determines how quickly the satellite moves around the earth. 7 9 km s 28 440 km h or 17 672 mph 1 h 24 min 18 sec 31 2 mj kg low earth orbit. As satellites get closer to earth the pull of gravity gets stronger and the satellite moves more quickly. M earth 5 98 x 10 24 kg r earth 6 37 x 10 6 m.

Find its period of revolution if r 6400 km. All you have to do is put in the numbers. Human made satellites typically orbit at heights of 400 miles from the surface of the earth about 640 kilometers or 6 4 10 5 meters. Assume mearth 5 98 1024 kg.

At what height above the earth is the free fall acceleration 15 of its value at the surface.
