1. A block with a speaker attached to it is connected to an ideal spring of constant k = 20.0 allowed to oscillate back and forth in front of a seated observer. The total mass of the block and sponker is 4.00 kg and the amplitude of the source's motion is 0.500 m. The speaker emits sound waves of frequency 430 Hz. The speed of sound in air is 343 m/s. a) Draw a free hody diagram, detailing all of the forces acting on the block. b) Determine the maximum speed of the source's motion, c) Determine the highest frequency heard by the observer sitting in front of the source.
