Problem 16.81

A bat locates insects by emitting ultrasonic chirps and then listening for echoes from the bugs. Suppose a bat chirp has a frequency of 25 kHz. How fast would the bat have to fly, and in what direction, for you to just barely be able to hear the chirp at 20 kHz?

Step-by-Step Solution:

Step 1 of 3

Chapter 3 – Vectors & TwoDimensional Motion (Projectile Motion)  Physical Quantity o Scalar Quantities  Have magnitude , but o particular direction  Including Time, Mass, People  Adds up numerically (Normal Addition) o Vector Quantities  Have both magnitude and direction (often given as an angle measured from the positive xaxis, or navigationally)  PAPER NOTES 1 o Distance and peed are Scalars o Displacement and elocity are Vectors  Vector Addition o CANNOT be added the same way as Scalars o Requires a diagram which is used to find the Resultant Vector o Addin
