A power boat of mass 500 kg iscruising at a constant speed of 8.9 m/s. The propeller provides adrive force of 765 N. The driver ofthe boat shuts off the engine, and the boat coasts to a halt.Assume -- contrary to fact -- that the resistive force due to thewater is constant, independent of the boat's speed.
