5. You are designing an airplane propeller that is to turn at 3500rpm (or revolutions per minute). The forward airspeed of the plane is to be 75.0m/s, and the speed of the tips of the propeller blades through the air must not exceed 300 m/s. (This is about 85% of the speed of the sound in air. If the speed of the propeller tips were greater than this, they would produce a lot of noise.) (a) What is the maximum possible propeller radius? (b) With this radius, what is the acceleration of the propeller tip?

A car that is about to enter a tunnel and is moving at a top speed of 50.0 [kph]. To signal that the car is coming, the car driver blows a horn, producing a sound of some frequency. At that time, the temperature of the air is about 20.0°C. What is the speed of sound in air at this temperature? If the sound is reflected back by a wall at the opening of the tunnel, what is the ratio of the incident frequency and the received frequency heard by the car driver?
