You are designing an airplane propeller that is to turn at 2400 rpm. The forward airspeed of the plane is to be 75.0 m/s, and the speed of the propeller tips through the air must not exceed 270 m/s (This is about 80% of the speed of sound in the air. If the propeller tips moved faster, they would produce a lot of noise) a. What is the maximum possible propeller radius? (1.03m) b. With this radius, what is the acceleration of the propeller tip? (6.5x104 m/s²)
