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.
Â­Sirius broadcasts satellite radio from three satellites, which were launched in 2000 from the Baikonur Cosmodrome in the Republic of Kazakhstan. The satellites orbit the Earth in an elliptical constellation, between 15,200 and 29,280 miles above the Earth's surface.efore the two companies merged, XM and Sirius went head-to-head signing radio celebrities, and the most famous -- or infamous -- of these was Howard Stern.
