Starting from rest at home plate, a baseball player runs to first base (90 ft away). He uniformly accelerates over the first 10.5 ft to his
maximum speed, which is then maintained until he crosses first base. If the overall run is completed in 3.8 seconds, determine his
maximum speed, the acceleration over the first 10.5 feet, and the time duration of the acceleration.
