Question 2 • Physics
Kinetic energy depends on both mass and speed: KE = ½mv². The motorcycle and pickup truck travel at the same speed, 25 m/s, so the heavier pickup truck has greater kinetic energy than the motorcycle. The compact car and minivan travel more slowly at 10 m/s, which makes their kinetic energy lower; therefore, the pickup truck traveling at 25 m/s is the best choice.
