The predominant frequency of a certan fire truck's siren is measured to be 1350 Hz by a person standing next to the parked fire truck. What frequency would you hear if the truck were stopped at a red light and you were moving away from it at 30 m/s? (You should probably have pulled over to the side of the road, but maybe you saw that the fire truck was turning left.) Sketch the situation, defining all of your variables.
What physics equation(s) will you utilize in order to solve this problem? For each equation you list, give a justification for why it applies to this situation.
Apply your equation(s) to solve the problem as an algebraic expression(s).
Calculate your numerical answer(s). Show the units of your answer(s), and how you got them
