Multiple Choice
Consider a meteoroid with a diameter of 10 cm and a mass of 2 kg that hits Earth head-on while traveling at a speed of 25,000 m/s.How many times larger or smaller is the meteoroid's kinetic energy compared to that of a typical train whose mass is 2 * 106 kg and speed is 25 m/s?
A) The meteoroid's kinetic energy is equal to that of the train.
B) The meteoroid's kinetic energy is 1,000 times less than that of the train.
C) The meteoroid's kinetic energy is 1,000 times greater than that of the train.
D) The meteoroid's kinetic energy is 106 times greater than that of the train.
E) The meteoroid's kinetic energy is 109 times greater than that of the train.
