Please show me how to do the following question:
Sonar is used to determine the speed of an object. A 40.0 khz signal is sent out, and a 42.0 khz signal is returned. if the speed of sound is 345 m/s, how fast is the object moving? Answer is 8.4 m/s. But I need an explanation step by step. The equation the instructor gave was change in frequency = 2f(v object / v wave) but I do not get the same answer. Thank you!
