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 585 gg falcon flying at 23.0 m/s flew into a 1.40 kg raven flying at 8.00 m/s . The falcon hit the raven at right angles to its original path and bounced back with a speed of 5.80 m/s. question  By what angle did the falcon change the raven's direction of motion?
