At a football tryout, a player runs a 40-yard dash in t₂ = 4.25 seconds. If the reaches his maximum speed at the 11-yard mark L₁ with a constant acceleration and then maintains that speed for the remainder of the run, determine his acceleration over the first 11 yards, his maximum speed, and the time duration of the acceleration.

Question
Your answer is partially correct. At a football tryout, a player runs a 40-yard dash in t2 = 4.25 seconds. If the reaches his maximum speed at the 11-yard mark L₁ with a constant acceleration and then maintains that speed for the remainder of the run, determine his acceleration over the first 11 yards, his maximum speed, and the time duration of the acceleration. t=0 Amswers: His acceleration: His maximum speed: The time duration of the acceleration: a= V = t = i 36 5.3255 2.0325 ft/sec² ft/sec sec
