Quizplus · Accepted Answer

The car accelerates from 5.0 m/s to 21 m/s at a constant rate of 3.0 m/s^2. To find the distance traveled, we can use the formula $d = \frac{v^2 - u^2}{2a}$, where $v = 21$ m/s is the final velocity, $u = 5.0$ m/s is the initial velocity, and $a = 3.0$ m/s^2 is the acceleration. Plugging in the values, we get $d = \frac{(21)^2 - (5)^2}{2 \times 3} = \frac{441 - 25}{6} = \frac{416}{6} = 69$ meters.
