The aircraft carrier John F. Kennedy has mass 7.4*10^7 kg. When its engines are developing their full power of 280000 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?
