What Is The Speed Of A Satellite Orbiting At That Height

All you have to do is put in the numbers.

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

Earth s own rotation at surface for comparison not an orbit 6 378 km. At what height above the earth is the free fall acceleration 15 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.

Find its period of revolution if r 6400 km. An artificial satellite is revolving around the earth in circular orbit at a height of 1000 km at a speed of 7364 m s. 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. 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.

Solution for at what height above the earth is the acceleration due to gravity 25 0 of its value at the surface. What is the speed of a satellite orbiting at that height. As satellites get closer to earth the pull of gravity gets stronger and the satellite moves more quickly. Speed orbital period specific orbital energy.

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. M earth 5 98 x 10 24 kg r earth 6 37 x 10 6 m. At an altitude of 124 miles 200 kilometers the required orbital velocity is a little more than 17 000 mph about 27 400 kph. 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.

What s the speed of such a satellite. Assume rearth 6 37 106 m. 465 1 m s 1 674 km h or 1 040 mph 23 h 56 min 62 6 mj kg. A satellite wishes to orbit the earth at a height of 100 km approximately 60 miles above the surface of the earth.

An earth orbiting satellite s motion is mostly controlled by earth s gravity. Determine the speed acceleration and orbital period of the satellite. Due to atmospheric drag satellites do not usually orbit below 300 km 190 mi. The height of the orbit or distance between the satellite and earth s surface determines how quickly the satellite moves around the earth.

Assume mearth 5 98 1024 kg.
