You attach a speaker to an air track cart and then attach the cart to one end of the air track by means of a spring and start the system oscillating by stretching the spring 0.697 m from its equilibrium position and then releasing it. The force constant for the spring is k = 46.8 N/m, the total mass of the speaker and air track cart are 4.00 kg, and the speaker emits sound with a frequency of 345 Hz. If your lab partner Pat stands at the end of the air track, determine the highest and lowest frequencies she hears. The speed of sound in air is 343 m/s. (Enter your answers to at least the nearest Hz.)

Two identical piano wires have a fundamental frequency of 640 Hz when kept under the same tension. What fractional increase in the tension of one wire would lead to the occurrence of 10 beats/s when both wires oscillate simultaneously.
A body is suspended vertically from an ideal spring of spring constant 3.4 N/m. The spring is initially in its relaxed position. The body is then released and oscillates about its equilibrium position. The motion is described by the following equa..
