At a football tryout, a player runs a 40-yard dash in t₂ = 4.15 seconds. If the reaches his maximum speed at the 15-yard mark L₁ with a constant acceleration and then maintains that speed for the remainder of the run, determine his acceleration over the first 15 yards, his maximum speed, and the time duration of the acceleration.
