Driving down a quiet street on a summer day with the car windows down, you see a convertible
approaching from the opposite direction, with the driver playing her car stereo loudly. Having a
well-trained musician’s ear, you notice that the song you hear is in a key one semitone (the
interval between two adjacent keys on a piano) above the key in which the song is typically
heard. You also know that to shift any note by one semitone, the frequencies must be related by
a factor of 1.06. Assume both drivers are traveling at the same speed, what is their speed?

Expert Solution

I have solved the problem using the simple Doppler Effect formula.

I will be happy to clear if there is any doubt.

You are driving at 90 miles/hour.  You suddenly see a Police car on the shoulder at 100 meters. How hard you need to hit the break (what should be your deceleration) to reduce you speed from 90 mi/h to 60 mil/s at the time you reach to the officer? Your reaction time, before stepping on the brake is 0.50 s 1 mile/h = 0.45 m/s
