Meteroids often move at high speeds relative to Earth. If meteroids approach Earth closely enough to hit our atmosphere, friction heats them and the radiate, causing a spectacular light display. If a 15 gram meteroid approaches at 50 km/s
A) find the meteroid's kinetic energy
B) How fast would a 14kg auto have to move to achieve the same KE
C) INCLUDE FREE BODY DIAGRAM
