A truck is traveling at 56 mi/h (25.2 m/s) down the interstatehighway where you are changing a flat tire. As the truckapproaches, the truck driver sounds an air horn, which has afrequency of 1.7E2 Hz. Enter scientific notation as1.23E4.

(a) What frequency do you hear?

(b) Suppose that you were driving your car at 58 mi/h whilethe truck driver blows his air horn after he passes you. What frequency would you hear?
