Ben and jerry compete in a 1.00 km race. Ben's strategy is to run the first 600 m of the race at a constant speed of 4.00 m/s, and then accelerate to his maximum speed of 7.50 m/s, which takes him 1.0 min, and then finish the race at that speed. Jerry decides to accelerate to his maximum speed of 8.00 m/s at the start of the race and to maintain that speed throughout the rest of the race. It takes Jerry 3.00 min to reach his maximum speed Assuming all accelerations are constant, who wins the race?
