A bat, moving at 4.50 m/s, is chasing a small flying insect.

(a) If the bat can only “see” insects larger than the wavelength of its 40.0 kHz chirp, what is the smallest size insect that the bat can see on a cool 18°C night?

(b) The bat hears an echo at 40.3 kHz off of one of the insects. What is the speed of the insect?

(c) Will the bat be able to catch up with the insect at its current speed? [8.54 ??, 3.2 ?? ]
