Bird Defense to protect their young in the nest, peregrine falcons will fly into birds of prey (such as ravens) at high speed. In one such episode, a 6()().g falcon flying at 20.0 m/s hit a l.50-kg raven flying at 9.0 m/s. The falcon hit 1he raven at right angles to its original path and bounced back at 5.0 m/s.
(These figures were estimated by the author as he watched this attack occur in northem New Mexico.)
(a) By what angle did the falcon change the raven's direction of motion?
(b) What was 1he raven's speed right after the collision?
