Two cars are going to race over a distance of 500 meters. The first car accelerates at 10.5 meters per second per second for 4.25 seconds then accelerates at 7.5 meters per second per second till it crosses the finish line. The second car accelerates at 9.5 meters per second per second for the first 3.5 seconds then at 8.5 meters per second per second till it crosses the finish line. What is the velocity of the winning car at the end of the race?
