Statement of a problem № 41720


The aircraft carrier John F. Kennedy has mass 7.4 X 107 kg. When its engines are developing their full power of 280,000 hp, the John F. Kennedy travels at its top speed of 35 knots (65 km/h). If 70% of the power output of the engines is applied to pushing the ship through the water, what is the magnitude of the force of water resistance that opposes the carrier s motion at this speed?
