1. The famous "Speed Racer" is driving his car at 30 miles per hour but he needs to reach a speed of 45 miles per hour if he wants to beat his rival in a race. Suppose that "Speed Racer" only has a clean 5 kilometer stretch of racetrack to accelerate to such a speed. a) What acceleration is necessary for Speed Racer's car to reach its final speed at the end of the racetrack? Assume a constant acceleration. b) How long does it take for the car to reach its final speed?
