A drag racing car takes off down a straight track from a dead stop. Its distance from the starting line is found to be r(t) = (8.50m/s³)t +(1.20m/s) t° a. Calculate the race car's average speed for t 0 to t 2 s. b. Calculate the race car's instantancous speed at t= 2.00 s.* c. Calculate the amount of time it takes for the dragster to travel one-quarter of a mile." A drag racing car takes off down a straight track from a dead stop.
