Peregrine falcons frequently grab prey birds from the air. Sometimes they strike at high enough speeds that the force of the impact disables prey birds. A 480 g peregrine falcon high in the sky spies a 240 g pigeon some distance below. The falcon slows to a near stop, then goes into a dive--called a stoop--and picks up speed as she falls. The falcon reaches a vertical speed of 45 m/s before striking the pigeon, which we can assume is stationary. The falcon strikes the pigeon and grabs it in her talons. The collision between the birds lasts 0.015 s. What is the final speed of the falcon and pigeon? Express your answer with the appropriate units. Ufp = Part B Value Fp,av = What is the average force on the pigeon during the impact? Express your answer with the appropriate units. μA Units Value ? Units ?

A 8000-N car is traveling at 50 km/h. It strikes a 12000-N car, which is stationary. The two cars stick together. Their common final speed (in m/s) is: 8.9 a O 7.8 .b O 6.7 4.5 .d O 5.6 .e O

Hunter aims his gun vertically and shoots a 465 g game, which is positioned, on a telephone pole. The bullet has a mass of 60 g and is traveling at a velocity of 450 m/s upwards just before it hits the target. The bullet passes through the target, emerging with a velocity of 295 m/s upwards. How high does the target rise after being hit by the bullet?

A person is crossing a bridge. The bridge is 3.2 meters long and is 25 kg. One side of the bridge rests on the ground while the other side of the bridge is elevated 25 degrees above the ground. The end of the bridge that is elevated is connected to a rope, which is attached to a overhanging section of a cliff. The person walking across is 62 kg, and walks three quarters of the way to the rope end of the bridge then stops. Please determine the magnitude of the force that the ground exerts on the bridge.

At the center of a 47.0 m diameter circular ice rink, a 56.0 kg skater traveling north at 2.60 m/s collides with and holds onto a 59.0 kg skater who had been heading west at 1.05 m/s. How long (in seconds) will it take them to reach the edge of the rink assuming negligible friction and drag?

A 980-kgkg sports car collides into the rear end of a 2500-kgkg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.9 mm before stopping. The police officer, estimating the coefficient of kinetic friction between tires and road to be 0.80, calculates the speed of the sports car at impact. v= ? m/s *0.40 and 0.76 m/s are wrong

An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.15 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 35.5 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target?

The superheroine Xanaxa, with a mass of 69.9 kg, is in a hair-raising chase after the 72.7-kg arch-villain Lexlax. She leaps from the ground to the top of a 195-m-high building, then dives off and comes to rest at the bottom of a 15.7-m-deep excavation, where she finds Lexlax and neutralizes him. Does all this bring about a net gain or a net loss of gravitational potential energy? Gain Loss By how much? Answer with a positive number. Take g = 9.81 m/s?. Number J

You are renting a cabin in lake Tahoe that is near a hill. Your car is outside and is 2000kg. An avalanche starts from rest down a 370 slope to the horizontal . The hill is 100m high. The mass of the snow coming down the hill is 3000kg. You can consider the hill to be frictionless. The snow collides with the car at the bottom of the hill and the car and the snow move together until they come to a stop after 48m due to a drag force. What was the drag force?
