3) A sports car is speeding toward you down the road. The car is traveling at 25.2 meters per second and the exhaust produces sound waves with a frequency of 845 Hz. Find the observed frequency as the car is driving towards you and when the car is driving away from you. How do they compare? Would you notice the difference in the sounds? Use 343 m/s for the speed of sound.

A car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by x(t)=bt2−ct3, where 2.30 m/s2 and c = 0.120 m/s3. Part A Calculate the average velocity of the car for the time interval t=0 to t=10.0 s. Part B Calculate the instantaneous velocity of the car at t=0. Part C Calculate the instantaneous velocity of the car at t= 5.00 s. Express your answer in meters...

You are driving down the road at 15.6 m/s (35 mph) when an ambulance passes you with its siren blaring. The ambulance siren produces a frequency of 700 Hz. As the ambulance approaches you from behind, you hear a frequency of 730 Hz . The speed of sound in air is 344 m/s. What is the speed of the ambulance? The positive direction points from your car (listener) toward the ambulance (source). Express your answer in meters per second.
