A boat moves through the water with two forces acting on it. One is a 1,700-N forward push by the water on the propeller, and the other is an 1,300-N resistive force due to the water around the bow.
(a) What is the acceleration of the 900-kg boat?
(b) If it starts from rest, how far will the boat move in 9.0 s?
(c) What will its velocity be at the end of that time?
