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 ?

Question

Transcribed Image Text:**Peregrine Falcons and Impact Dynamics**
**Scenario Overview:**
Peregrine falcons are known to capture prey birds mid-air, sometimes reaching high speeds that their impact can disable these birds. A 480 g peregrine falcon spots a 240 g pigeon below. The falcon initially slows down and then accelerates into a dive, known as a stoop, reaching a vertical speed of 45 m/s before striking the pigeon, which is initially stationary. Upon collision, the falcon captures the pigeon with its talons. The impact duration is 0.015 seconds.
**Problem Statements:**
**Part A:**
- **Question:** What is the final speed of the falcon-pigeon system after impact?
- **Requirement:** Provide the answer with appropriate units.
- **Input Box:**
- Symbol: \( v_{fp} = \)
- Two fields to enter numerical value and units.
**Part B:**
- **Question:** What is the average force experienced by the pigeon during the collision?
- **Requirement:** Provide the answer with appropriate units.
- **Input Box:**
- Symbol: \( F_{p,av} = \)
- Two fields to enter numerical value and units.
This exercise applies principles of momentum conservation and force calculations during a collision event.
