A drag racer starts from rest and accelerates at 8.0 m/s² for the entire distance of 300 m.What is the velocity of the race car at the end of the run? A)83 m/s B)69 m/s C)52 m/s D)35 m/s E)59 m/s

To find the final velocity, we use the kinematic equation: v² = u² + 2as, where u = initial velocity = 0, a = acceleration = 8.0 m/s², and s = distance = 300 m. Solving for v gives v = √(0 + 2 * 8.0 * 300) = √4800 = 69.28 m/s, which rounds to 69 m/s.
