Who will win the race?
  1. The red car is 6,000 meters from the finish line and is traveling at a constant speed of 60 meters/second at a certain instant in time. The green car is 9,000 meters away from the finish line and is accelerating from rest at this very same instant in time. Who will win the race if the green car is accelerating at a rate of 4 meters/second2? Who would have won the race if the red car would have been traveling at a constant speed of 90 meters/second?
  2. The red car is 8,000 meters from the finish line and is accelerating from rest at a rate of 2 meters/second2 at a certain instant in time. The green car is 9,000 meters from the finish line and is traveling at a constant speed of 90 meters/second at this very instant in time. Who will win the race?
