KE = 1/2(100 kg)(100 m/s)^2 = 500000 Joules ----------------------- KE = 1/2(100 kg)(50 m/s)^2 = 125000 Joules ---------------------- 5â¦00000 Joules/125000 Joules = 4 ------ The kinetic energy is reduced by a factor of 4 because the speed is squared.
Earth, the fifth-largest of the eight planets in the Solar System belongs to the Milky Way galaxy and is orbiting about 28,000 light years from the center of the galaxy. It is believed that currently it lies about 20 light years above the galaxy's equatorial plane in the Orion spiral arm.
Medium Earth Orbit. Medium Earth Orbit (MEO) refers to a satellite which orbits the earth at an altitude below 22,300 miles (geostationary orbit) and above the altitude of Low Earth Orbit (LEO) satellites. Medium Earth Orbit represents a series of tradeoffs between geostationary orbit (GEO) and Low Earth Orbit (LEO).
