Assume the speed of sound in air is 343 m/s. What frequency do you hear as the ambulance approaches you? What frequency do you hear as the ambulance moves away from you?

Two blocks, each with a mass of 12 kg, are placed on a frictionless horizontal surface and are connected by a massless spring with a spring constant of k=220 N/mk=220 N/m. If you apply a horizontal force of 18 N to one of the blocks, then how much will the spring compress as the boxes accelerate?
