A microphone is attached to a spring that is suspended from the ceiling. Directly below on the floor is a stationary 440 Hzsource of sound. The microphone vibrates up and down in simple harmonic motion with a period of 2.0 s. The difference between the maximum and minimum sound frequencies detected by the microphone is 2.1 Hz. Ignoring any reflections of sound in the room and using 343 m/s for the speed of sound, determine the amplitude of the simple harmonic motion
the average speed of an object over a given time duration is 6 m/s. If it travels first half of the duration with a constant speed 4 m/s, its speed during the next half duration is
