1. The problem statement, all variables and given/known data A power boat of mass 475 kg is cruising at a constant speed of 8.9 m/s. The propeller provides a drive force of 765 N. The driver of the boat shuts off the engine, and the boat coasts to a halt. Assume-contrary to fact-that the resistive force due to the water is constant, independent of the boat's speed. 2. Relevant equations F=ma a=velocity/time v=d/t 3. The attempt at a solution I divided Force by mass to get acceleration since F=ma. Then using the acceleration formula a=d/t i calculated time. Using that time i calculated distance useing the velocity formula v=d/t. I got 49.183 meters and 5.526 seconds. I got this answer wrong.
