A gas-powered model airplane has a mass of 2.50 kilograms. A student exerts a force on a cord to keep the airplane flying around her at a constant speed of 18.0 meters per second in a horizontal, circular path with a radius of 25.0 meters. Calculate the magnitude of the centripetal force exerted on the airplane to keep it moving in this circular path. Calculate the kinetic energy of the moving airplane.
