A boat moves through the water with two forces acting on it, Ask an Expert

Academics

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?
