Atypical meteor that hits the earth's upper atmosphere has a mass of only 2.5 g, about the same as a penny, but it is moving at an impressive 40 km/s. as the meteor slows, the resulting thermal energy makes a glowing streak across the sky, a shooting star. the small mass packs a surprising punch.
at what speed would a 900 kg compact car need to move to have the same kinetic energy?
