A sports car races a stock car. The sports car can accelerate at 16.0 m/s^2 while the stock car can only accelerate at 12.0 m/s^2. They both start from rest (0) but the stock car gets a 1.00 s head start ahead of the sports car. Find the time it takes the sports car to catch up to the stock car and the distance they travel before they are next to each other and the speed of each at that point.
