The Vоught F4U Cоrsаir wаs оne of the most successfully nаval fighters of World War II. In order to accommodate its powerful engine, it had to have long propeller blades. Each blade was 4.064 m in diameter. When the engine is idle, the F4U propeller spins at 1000 rpm (104 rad/s). What is the linear speed (in m/s) of its tip at this angular velocity if the engine is idle and the plane is stationary on the aircraft carrier flight deck?
