8. Mr. McCloskey is driving his truck along a straight road when he notices a small dark object 500 ft ahead. He steps on the brakes, then recognizes that the object is a duck standing in the middle of the road. The truck records his speed every 2 seconds after he applies the brakes until he stops after 10 seconds. time t (sec) 02 4 6 8 10 speed (ft/sec) 100 80 50 25 10 0 Is it possible that Mr. McCloskey hit the duck? Find lower, midpoint, and upper estimates for the total distance traveled by the truck before coming to a stop. Assume that the speed of the truck decreased throughout the 10-second period but not necessarily at a steady rate.
