Question

A bat is chasing a flying bug. The bat is moving at 4.50 m/s, and can only see the bug when the wavelength is larger than its 40.0 kHz chirp.

a. What is the smallest size bug the bat can see on a 18°C night? (Answer: 8.54 mm)

b. The bat hears an echo at 40.3 kHz off the bug. What is the speed of the bug? (Answer: 3.2 m/s)

c. Will the bat be able to catch up with the bug at its current speed?
