A car starts from rest and accelerates uniformly at 2.0 m/s² for 5.0 seconds. What is the car's final velocity?

Core Concept

Using the kinematic equation v = v₀ + at, where v₀ is the initial velocity (0 m/s since the car starts from rest), a is the acceleration (2.0 m/s²), and t is the time (5.0 s), we get v = 0 + (2.0)(5.0) = 10.0 m/s. Option A is incorrect because it only gives the acceleration value without accounting for time. Option B is incorrect as it appears to be using the time value without the acceleration. Option D is incorrect as it seems to be multiplying acceleration, time, and another factor (possibly distance).
