Question: Because accelerating while its horn is blowing. Just after the car passes a stationary person, the person has a frequency of 9 6 8 Hz

Because accelerating while its horn is blowing. Just after the car passes a stationary person, the person has a frequency of 968 Hz.10.1 seconds later, the frequency heard by the person has decreased to 922 Hz. When the car stationary, its horny miss a sound whose frequency is 1020 Hz. The speed of sound is 343 m/s. What is the acceleration of the car? Assume that the velocity of the car is always in a positive direction.
