On a hot 98.60F (310 K) day at a racetrack, a Formula One racecar is traveling at a speed of 1.75 x 10 mph (78.2 m/s) away from a stationary siren emitting sound waves at a frequency of 3.05 x 102 Hz. (a) Determine the sound speed for the given temperature. (Enter your answer to at least 1 decimal place.) X m/s (b) What frequency did the racecar driver hear? X Your response differs from the correct answer by more than 10%. Double check your calculations.
