1. Two 0.85-m-long pendulums hang side by side. The masses of the pendulum bobs are 75 g and 95 g. The lighter bob is pulled aside until its string is horizontal and is then released from rest. It ‘swings down and collides elastically with the other bob at the bottom of its arc. To what height does each bob rebound?
2. An eagle s dive. When diving for prey, bald eagles can reach speeds of 200 mph (322 km/h). Suppose a 6.0-kg eagle flying horizontally (322 km/h) at suddenly grasps and holds a stationary 5.0-kg jackrabbit in her talons.
(a) What's the eagle s speed just after grasping the rabbit?
(b) What percent of her kinetic energy is lost during the process?
(c) What would be the eagle s final speed if the rabbit were initially running toward her at 2.0 m/s?
