2. 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 600 gram falcon flying at \( 20.0 \mathrm{~m} / \mathrm{s} \) due south ran into a 1.50 kg raven flying at \( 9.00 \mathrm{~m} / \mathrm{s} \) due east. The falcon bounced back with a speed of \( 5.00 \mathrm{~m} / \mathrm{s} 30^{\circ} \) east of north. (These figures were estimated by an author of another physics textbook as he watched this attack occur in northern New Mexico.) (a) What is the net velocity of the raven after the collision? (b) What direction is the raven moving after the collision? (c) How much mechanical energy is lost during this collision?

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 600-g falcon flying at 20.0 m/s hit a 1.50-kg raven flying at 9.0 m/s. The falcon hit the 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 northern New Mexico.) (a) By what angle did the falcon change the raven's direction of motion? (b) What was the raven's speed right after the collision?

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 $570 \mathrm{~g}$ falcon flying at $18.0 \mathrm{~m} / \mathrm{s}$ hit a $1.40 \mathrm{~kg}$ raven flying at $9.0 \mathrm{~m} / \mathrm{s}$. The falcon hit the raven at right angles to its original path and bounced back at $5.0 \mathrm{~m} / \mathrm{s}$. (These figures were estimated by the author as he watched this attack occur in northern New Mexico.) (a) By what angle did the falcon change the raven's direction of motion?
