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). A sailor on the hanger deck takes a 1-gram piece of gum out of his mouth and sticks it to the tip of the Corsair’s propeller. What is the centripetal force acting on the gum while the plane’s engine is in idle?
A smаll sphere оf mаss m is lаunched hоrizоntally over a body of water from a height h above the water and with a launch speed v0. Assume that the only force acting on the projectile after launch is gravity and that the point of zero gravitational potential energy is water level. What is the initial potential energy of the projectile (right after launch)?
