At rest, a car’s horn sounds the note of A (440 Hz). The horn is sounded while the car is moving down the street. A bicyclist moving in the same direction as the car hears a frequency of 475 Hz. Knowing that the bicyclist is moving at one fifth the speed of the car, determine the speed of the car and explain whether the cyclist is ahead of or behind the car. The air temperature is 17°C.

A bicyclist is pedaling down a road at 8 m/sec. A car approaches him from behind. When the car is preparing to pass he sounds his horn. At first the bicyclist hears a frequency of 520 HZ but the sound appears to drop in frequency to 470 HZ after the car passes. a) How fast is the car moving? (v sound = 340 m/sec)(answer to nearest whole number) 10 b) what is the actual frequency of the horn (don't assume...
