A boy is riding on a skateboard and playing a guitar at the same time. He is approaching to you with a speed v = 10 m/s. Use the speed of sound, v, = 343 m/s. While the skateboarder is approaching to you and playing a middle C (f = 264 Hz), the wind blows from you towards the skateboarder. The wind's speed is 5m/s. %3D Estimate the frequency you hear. Express your answer to three significant figures. The effect might not be large.
