four vehicles are traveling on the same road. which vehicle most likely has the greatest kinetic energy?\n a compact car traveling at a velocity of 10 m/s\n a pickup truck traveling at a velocity of 25 m/s\n a minivan traveling at a velocity of 10 m/s\n a motorcycle traveling at a velocity of 25 m/s
Answer
Explanation:
Step1: Recall kinetic energy formula
Kinetic energy $K = \frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity.
Step2: Compare masses and velocities
Among the vehicles, pickup truck and minivan are heavier than compact - car and motorcycle. The pickup truck has a velocity of 25 m/s and the minivan has a velocity of 10 m/s. Since kinetic energy is proportional to both mass and the square of velocity, the pickup truck with a relatively high velocity and large mass is likely to have the greatest kinetic energy.
Answer:
a pickup truck traveling at a velocity of 25 m/s
