A drag racer starts from rest and accelerates at 8.0 m/s2 for the entire distance of 400 m (1/4 mile). What is the speed of the race car at the end of the run? Answer: The speed of the race car is 80 m/s Explanation: Here, we are going to solve for the speed of the race car at the end of the run or its final velocity . In this problem, we are going to use the concept of Straight line motion . For the formula, we will use: V² = Vo² + 2as where V is the final speed of the race car, unit is in m/s Vo is the initial speed of the race car, unit is in m/s a is the acceleration, unit is in m/s² s is the entire distance traveled by the race car, unit is in meter, m For the given information Vo = 0 because it starts from rest a = 8 m/s² s = 400 m V = ? Solving the problem V² = Vo² + 2as V² = 0 + 2(8 m/s²)(400 m) V = V = 80 m/s Therefore, the speed of the race car at the end of the run is 80 m/s .
