Collaborative Train Problem

A train blows its horn as it approaches downtown Parkville. The horn produces a tone of 1600 Hz and the train travels at a speed of 55 mph. (convert to SI).

(a) Find the tone frequency that is heard by an observer standing near the tracks downtown.

(b) What is the Beat frequency heard by the train conductor (yes he can hear it) due to the reflected sound of the horn off the building?

Work in groups. Draw picture ask questions in class. You will turn this in as a group Next week.
