Question
A boat moves through the water with two
forces acting on it. One is a 2.32×10^3 N
forward push by the motor, and the other is a1.79×10^3 N resistive force due to the water.What is the acceleration of the 1279.5 kg boat?

2.32 - 1.79 = .53
so
F = ma
.53 * 10^3 = 1279.5 a
a = .414 m/s^2
By the way this is not really true because water is accelerated along with the boat hull, making its mass appear larger. In hydrodynamics this is often called "added mass"
