Questions #17-18: A loud, single-pitch ambulance siren has a rest frequency of 650. Hz. Along a long
straight road, suppose that you are initially located to the left of the ambulance. The speed of sound in air is
335 m/s.
.
18. New scenario: If the ambulance is speeding to the right at 39.9 m/s, while you are also traveling to the
right at 10.8 m/s, what sound frequency will you hear?
(Laulima contains a
unique randomized value for both speeds.)
Calculate and enter your final answer to at least 3 significant figures. There is no penalty for including too
many significant figures, but rounding to too few sig figs may cause Laulima to judge your answer to be
wrong.
Do NOT enter units with your answer; enter only a numerical response. Laulima will count non-numerical
answers as incorrect.
Partial credit is NOT possible.
