A500,000 kg cargo ship is traveling at 75 km/h when its engine is shut off. the magnitude of the frictional force between boat and water is proportional to the speed v of the boat: f k = 85v, where v is in meters per second and f k is in newtons. find the time in hours for the ship to slow to one-third of its original speed because of the friction with the water.
