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.
