3 cars, X,Y,and 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 force exerted on each car is identical. After 10 seconds, rank the momentum of the cars?
*Answer - All cars have the same momentum - I need to know why?

Simply because the momentum is the product of mass x velocity.
As a greater mass will accelerate more slowly, it will not gain the same velocity as a lighter mass in the same time. But the product of (mv) is identical for any mass subjected to the same acceleration.
