The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at ??,2=17.5 m/s when the eagle swoops down, grabs the pigeon, and flies off. At the instant right before the attack, the eagle is flying toward the pigeon at an angle θ=47.1° below the horizontal and a speed of ??,1=42.1 m/s. What is the speed of the eagle immediately after it catches its prey? Speed: What is the magnitude of the angle, measured from horizontal, at which the eagle is flying immediately after the strike?

2. In a scifi movie about astronauts on a space station, one of the astronaut's safety line is cut while on a space walk. The astronaut, who 10 meters from the shuttle and is moving 0.1 m/s away from it, finds that the suit's thruster pack has also been damaged and no longer works and that only 30 seconds of air remains. To get back to the shuttle, the astronaut unstraps a 10-kg tool kit and throws it away with a speed of 5 m/s. In the scene, the astronaut, who has a mass of 100 kg without the toolkit, survives. Is this reasonable?
