1. The following graph represents the perceived frequency of a car as it passes a student.
(a)If the true frequency of the car's horn is 170 Hz, how fast was the car traveling (in m/s)? (Assume the speed of sound is 343 m/s.)
m/s
(b) On the graph above, draw a line demonstrating the perceived frequency for a car traveling twice as fast. Label all intercepts, maximums, and minimums on the graph. (Assume the perceived frequency for the car traveling twice as fast is in blue.)

A train is moving parallel and adjacent to a highway with a constant speed of 32 m/s.
A train is moving parallel and adjacent to a highway with a constant speed of 32 m/s. A car is traveling in the same direction as the train at 64 m/s. The car's horn sounds at 520 Hz and the train's whistle sounds at 320 Hz. When the car is behind the train what frequency does an occupant of the car observe for the train whistle? The speed of sound is 343 m/s. Answer in units of Hz. When the car is in...

A car is parked 20.0 m directly south of a railroad crossing. A train is approaching the crossing from the west, headed directly east at a speed of 55.5 m/s. The train sounds a short blast of its 312-Hz horn when it reaches a point 20.0 m west of the crossing. What frequency does the car's driver hear when the horn blast reaches the car? The speed of sound in air is 343 m/s. (Hint: Assume that only the component...
