Question

four vehicles are traveling on the same road. which vehicle most likely has the greatest kinetic energy? a compact car traveling at a velocity of 10 m/s; a pickup truck traveling at a velocity of 25 m/s; a minivan traveling at a velocity of 10 m/s; a motorcycle traveling at a velocity of 25 m/s

Explanation:

Kinetic energy formula is $KE = \frac{1}{2}mv^2$, where $m$ is mass and $v$ is velocity. Kinetic energy depends on both mass and velocity (velocity has a squared effect). A pickup truck has more mass than a motorcycle, and its velocity (25 m/s) is higher than the lower - velocity vehicles (compact car, minivan at 10 m/s). Comparing the pickup truck (higher mass, relatively high velocity) and motorcycle (lower mass, same high velocity), the pickup truck will have greater kinetic energy due to its larger mass, combined with a relatively high velocity. Also, compared to the compact car and minivan (lower velocity), the pickup truck's higher velocity (and reasonable mass) gives it more kinetic energy.

Answer:

a pickup truck traveling at a velocity of 25 m/s
