four vehicles are traveling on the same road. which vehicle most likely has the greatest kinetic energy?\no a compact car traveling at a velocity of 10 m/s\no a pickup truck traveling at a velocity of 25 m/s\no a minivan traveling at a velocity of 10 m/s\no a motorcycle traveling at a velocity of 25 m/s

four vehicles are traveling on the same road. which vehicle most likely has the greatest kinetic energy?\no a compact car traveling at a velocity of 10 m/s\no a pickup truck traveling at a velocity of 25 m/s\no a minivan traveling at a velocity of 10 m/s\no a motorcycle traveling at a velocity of 25 m/s

Answer

Explanation:

Step1: Recall kinetic - energy formula

The formula for kinetic energy is $KE=\frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity. Kinetic energy depends on both mass and velocity.

Step2: Compare masses and velocities

Among the given vehicles, a pickup truck and a minivan are generally heavier than a compact car and a motorcycle. The pickup truck and the motorcycle have a velocity of 25 m/s, and the compact car and the minivan have a velocity of 10 m/s. Since the pickup truck has a relatively large mass and a high velocity (25 m/s), compared to the other vehicles, it is likely to have the greatest kinetic energy.

Answer:

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