A wireless transmitting microphone is mounted on a small platform that can roll down an incline, directly away from a loudspeaker that is mounted at the top of the incline. The loudspeaker broadcasts a tone that has a frequency of 1.000 x 104 Hz, and the speed of sound is 343 m/s. At a time of 1.5 s following the release of the platform, the microphone detects a frequency of 9952 Hz. At a time of 3.5 s following the release of the platform, the microphone detects a frequency of 9888 Hz. What is the acceleration a (assumed constant) of the platform?
