Determine the position function for t2 0. b. How far does the racer travel in the first 45? see 50 ܐܗ c. At this rate, how long will it take the racer to travel 4 d. How long will it take the racer to travel 300 11? e. How far has the racer traveled when it reaches a speed of 177 tus? sees See se a. The position function for t20 is st)- b. In the first 4 s, the racer travels In (Simplify your answer. Type an integer or decimal rounded to three decimal places as needed) Sees C. At this rate, it will take the racers to travel (Do not round until the final answer. Then round to three decimal places as needed d. It will take the racers to travel 300 (Do not round until the final answer. Then found to three decimal places as needed) e. When the racer reaches a speed of 177 fts, it has traveled (Do not round until the final answer. Then found to three decimal places as needed)

Answer 1

vlogo ,5100 las alt)= 7841/5 Nit) st Sct) 785 3972 so s(t) = 3at والمحال (6) S(4)= 39/42 In the first is the racer travels 624 ft 10 hile = 5000ft S980 ft = 1320ft 113205 - 1320 to relef set It will take the souris.818.s to tare Imi (2) 300 = 39 t t - 300 t-d.774 It will take the racer 1204 s to travel zooft te 177=28t - to in 78 2/154.482 ft It has traneled 154.482 ft say - 39 128
