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 1.40 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.) By...
Momentum
Protecting his nest, a 600- peregrine falcon rams a marauding 1.5- raven in midair. The falcon is moving at 20.0 , and the raven at 9.00 at the moment of impact. Thefalcon strikes the raven at right angles to the raven's direction of flight and rebounds straight back with a speed of 5.00 . By what angle does the impact change theraven's direction of motion?Now, use the diagram below to draw before-and-after sketches for the collision. The dots represent the...

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?

15. Two automobiles traveling at right angles to each other collide and stick together. Car A has a mass of 1000 kg and had a speed of 25 m/s before the collision. Car B has a mass of 1500 kg. The skid marks show that, immediately after the collision, the wreckage was moving in a direction making an angle of 40° with the original direction of car A. What was the speed of car B before the collision, assuming that...

10.51 A uniform, 4.5-kg, square, solid wooden gate 1.5 m on each side hangs vertically from a frictionless pivot at the center of its upper edge. A 1.1-kg raven flying horizontally at 5.0 m/s flies into this door at its center and bounces back at 2.0 m/s in the oppo- site direction. (a) What is the angular speed of the gate just after it is struck by the unfortunate raven? (b)During the collision, why is the...

A bowling ball (mass:6.5 kg) is thrown down a bowling alley with a speed of 8 m/s. where it has an off center collision with a bowling pin (mass: 1.5 kg). After the collision, the bowling ball moves off to the right of the original path of motion with a reduced speed of 6.2 m/s at an angle of 11.3 degrees as shown, while the bowling pin is deflected to an angle of 32.3 degrees to the left of the...

A 1100 kg car traveling initially with a speed of 26.00 m/s in an easterly direction crashes into the back of a 9 450 kg truck moving in the same direction at 20.0 m/s. The velocity of the car right after the collision is 18.0 m/s to the east. (a) What is the velocity and direction of the truck right after the collision? (Give your answer to at least four significant figures.) (b) What is the change in mechanical energy...

A 73.3-kg linebacker ("X") is running at 6.71 m/s directly toward the sideline of a football field. He tackles a 91.7-kg running back ("O") moving at 8.61 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision both players momentarily leave the ground and go out-of-bounds at an angle φ relative to the sideline, as shown in the diagrams below. What is the common speed of the players, immediately after...

0.200 kg stone rests on a frictionless horizontal surface. A buffet of mass 8.60 g traveling horizontally at 360 m/s. takes the stone and rebounds horizontally at right angles to its original direction with a speed of 250 m/s. Compute the magnitude of the scene affect it is struckCompute the direction of the velocity of the stone after it is struck Is the collision perfectly?
