Peregrine falcons frequently grab prey birds from the air, as bi0 in example 9.10. sometimes they strike at high enough speeds that the force of the impact disables prey birds. a 480 g per- egrine falcon high in the sky spies a 240 g pigeon some dis- tance below. the falcon slows to a near stop, then goes into ve-called a stoop-and picks up speed as she falls. the n 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 falco birds lasts 0.015 s. a. what is the final speed of the falcon and pigeon? b. what is the average force on the pigeon during the impact?

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a. water evaporates, which favors the formation of h2co3. b. pressure decreases, which favors the formation of h2co3. c. the open container warms up, which causes more gas to escape. d. co2is removed, which favors the formation of h2co3.
