5pts) A dragster accelerates at a(t) = 60 /min 2. Assume that v(0) = 0 and s(0) = 0. a. Find the position function s(t) for the position of the dragster after t seconds (feet down the track). b. How fast is the drag racer going when it crosses the finish line 1000 ft down the track? c. What is the average of the velocity of the dragster over the course of the race (from start to when it crosses the finish line)
