An eagle perched on a tree limb 19.5 m above the water spots a fish swimming near the surface. The eagle pushes off from the branch and descends toward the water. By adjusting its body in flight, the eagle maintains a constant speed of 3.10 m/s at an angle of 20.0 degrees below the horizontal.
(a) How long does it take for the eagle to reach the water?
(b) How far has the eagle traveled in the horizontal direction when it reaches the water?
