At a football tryout, a player runs a 40-yard dash in t2 = 4.65 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. L1 t=0 Amswers: His acceleration: a= ft/sec2 His maximum speed: V = i ft/sec The time duration of the acceleration: t= i sec
