The mass of a pigeon hawk is twice that of the pigeons it hunts. Suppose a pigeon is gliding north at a speed of ?P=18.9 m/s when a hawk swoops down, grabs the pigeon, and flies off, as shown in the figure. The hawk was flying north at a speed of ?H=37.0 m/s, at an angle ?=45∘ below the horizontal at the instant of the attack. What is the birds' final speed ?f just after the attack

The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at 17.7 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 theta = 41.5 degree below the horizontal, and a speed of 36.7 m/s. What is the speed of the eagle immediately after it catches its prey? What is the magnitude...
The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at 0.2 = 18.1 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 0 = 62.7° below the horizontal and a speed of 0.1 = 35.9 m/s. What is the speed of the eagle immediately after it catches its prey? speed:...
The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at V12 = 17.7 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 0 = 49.1° below the horizontal and a speed of v,1 = 37.3 m/s. What is the speed of the eagle immediately after it catches its prey? speed:...
The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at Vi,2 = 17.3 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 0 = 55.1° below the horizontal and a speed of vi,1 = 41.5 m/s. What is the speed of the eagle immediately after it catches its prey? V:...
The mass of a particular eagle is twice that of a hunted pigeon. Suppose the pigeon is flying north at Vi,2 = 16.9 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 0 = 58.3° below the horizontal and a speed of vi,l = 41.9 m/s. What is the speed of the eagle immediately after it catches its prey? V.2...
Birds have evolved to the ability to control their motions through the air by controlling the forces exerted on their bodies by the air; the contact forces on a bird by the air plus the force of gravity on the bird by the Earth determine the change in motion of the bird at any instant of time. In this problem, you will be asked to use what you know about acceleration to track the motion of a diving hawk. A...

1. A Vulcan spaceship has a mass of 6.50 × 104 kg and a Romulan spaceship is twice as massive. Both have engines that generate the same total force of 9.50 × 106 N. If each spaceship fires its engine for the same amount of time, starting from rest and ignoring any change in mass due to whatever is expelled by the engines, calculate the energy of the Vulcan spaceship if the engines are fired for 103 s. 2. A...
