Question
34. A block with a speaker bolted to it is connected to aspring having spring constant k = 20.0 N/m. The total mass of theblock and speaker is 5.00kg, and the amplitude of this unit'smotion is 0.500m. a)The speaker emits sound waves of frequency 440 Hz. Determinethe highest and lowest frequencies heard by a person standing tothe right of the speaker. Please help. I will rate well as always. 34.

Max speed of oscillator = A k / m = 0.500 * 20.0 / 5.00 = 2.00 m/s
.
highest freq is heard from doppler shift when sourcemoves toward listener at 2.00 m/s.
