A car starting from rest accelerates uniformly at 3 m/s^2 for 2 seconds. What is its final velocity?

Explanation:
With constant acceleration, final velocity equals initial velocity plus acceleration times time. The car starts from rest, so v0 = 0. It accelerates at 3 m/s^2 for 2 s, giving v = 0 + (3)(2) = 6 m/s. Therefore, the final velocity is 6 meters per second. The other numbers would require a different initial speed or a different time, which aren’t given.
