SUMMARY
The problem involves a cyclist and a car approaching each other, with the car emitting a sound at 500 Hz and the cyclist perceiving it at 535 Hz. The correct approach to solve this involves using the general Doppler effect formula: f' = f(V + Vr) / (V - Vs), where both the source and receiver are in motion. The calculated speed of both the cyclist and the car is 11.6 m/s, confirming the expected result. This demonstrates the importance of applying the correct Doppler effect formula when both the source and receiver are moving.
