Computer games can simulate an encounter between predator and prey. The prey will retaliate to protect its young ones while the predator attacks. In one simulation, a 1.10 kg duck is chasing a 2.80 kg eagle. The duck, flying at 8.90 m/s, hits the eagle perpendicularly and bounces back at 4.80 m/s. If the eagle was flying at 14.8 m/s before the collision, what is the change in its direction of motion (in degrees)?
