question 33

Multiple Choice

Consider a meteoroid with a diameter of 10 cm and a mass of 2 kg that hits the 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.
