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:...

Peregrine falcons often grab their prey in flight. A falcon, flying at 18 m/s, swoops down at a 45° angle from behind a pigeon flying horizontally at 9.0 m/s. The falcon has a mass of 0.80 kg and the pigeon a mass of 0.36 kg. (a) Draw a before-and-after visual overview of the problem statement. (b) Calculate magnitude and direction of the the velocity of the falcon (now holding the pigeon) immediately after impact?

need help with this two questions, please !!
Two ice skaters, Daniel (mass 60.0 kg) and Rebecca (mass 45.0 kg), are practicing. Daniel stops to tie his shoelace and, while at rest, is struck by Rebecca, who is moving at 13.0 m/s before she collides with him. After the collision, Rebecca has a velocity of magnitude 7.00 m/s at an angle of 54.1" from her initial direction. Both skaters move on the frictionless, horizontal surface of the rink. What is...

8. A boat is heading due north as it crosses a wide river with a speed of 10.0 km/h relative to the water. The river has a current such that the water moves with a uniform speed 5.00 km/h due east. Determine the magnitude and direction of the boat's velocity with respect to an observer on the riverbank (5 points) A plane maintains a speed of 630 km/h relative to the air it is flying through, as it makes a...
