Three cars, car X , car Y , and car Z , begin accelerating from rest at the same time. Car X is more massive than car Y , which is more massive than car Z . The net accelerating force exerted on each car is identical. After 10 seconds, which car has the most amount of momentum?

Question

Three cars, car  X , car  Y , and car  Z , begin accelerating from rest at the same time. Car  X  is more massive than car  Y , which is more massive than car  Z . The net accelerating force exerted on each car is identical. After 10 seconds, which car has the most amount of momentum?

Quizplus · Accepted Answer

Since the net accelerating force and the time period are the same for all cars, according to the equation $p = Ft$, where $p$ is momentum, $F$ is force, and $t$ is time, they all have the same amount of momentum.
