Chapter 2.6, Problem 6EYU
A submerged alligator swims directly toward two unsuspecting ducks. The equation of motion of the alligator is xa = (0.25 m/s2) t2, the equation of motion of duck 1 is xd1 = 3 m − (1.5 m/s)t, and the equation of motion of duck 2 is xd2 = 3 m + (1 m/s) t. Which duck does the alligator encounter first?
