Calculating Water Resistance for a Rowboat with Known Forces

[uzboi]

Homework Statement

285 kg rowboat being pushed by a forward force of 112 N from the paddles. If its is accelerating at 0.120 m/s(squared) how much water resistance is it experiencing? (assume gravity and buoyancy cancel each other)

Given:
a = 0.120 m/s (2)
Forward force = 112 N
Mass = 285 kg

Homework Equations

unsure, just confused.

The Attempt at a Solution

Do not understand where to start.

Start with Newton's Second Law. You know that the *net* force on the boat is equal to the mass times the acceleration. You know the acceleration. From this, you can figure out what the net force should be.

Thanks. I got the answer and also understand it :D
