Question

PART A: We can model the dive of a peregrine as beginning from rest and falling vertically. (In reality, there is horizontal motion, but it isn't very important to understanding the dive speed.) The peregrine is initially in free fall, but as it falls faster and faster, it encounters more and more air drag. Eventually, the peregrine falls at some maximum speed, given its size, shape, and the air it's falling through. This maximum speed is the falcon's terminal velocity. Match each plot to whether it shows the height, speed, or magnitude of acceleration of a peregrine falling through air, starting from rest, as a function of time. These plots only show the portion of the dive while the peregrine is approaching terminal velocity. They do not show the bird pulling out of the dive, capturing prey, landing on the ground, etc. (A) height (B) speed (C) acceleration (magnitude) PART B: Draw a plot of the kinetic, thermal, gravitational potential, and total energies as a peregrine falcon dives, starting from rest and reaching terminal velocity. Start your plots right when the falcon starts diving. Stop the plots before the falcon pulls out of its dive. Your drawing should show four curves, one for each energy you're plotting. The curves should all be plotted on the same set of axes. Label the curves according to which type of energy they represent. You should also label the axes, but you don't need a scale for them. The roiling air behind the falcon technically has kinetic energy, but in a matter of seconds, that kinetic energy will be dissipated to thermal energy, so you can count any energy in the air as thermal energy in this problem. For thermal energy, draw the change in thermal energy from the time that the falcon starts diving, so this curve should begin at zero. Your plot can be qualitative, but should show the trend in each type of energy.
