A 1200 kg boat accelerates steadily at 0.05 m/s^2 in a straight line . Are the forces on this boat balanced or unbalanced?

What do you think? Honestly, these are not hard questions.
I have no clue we never covered it in class!
Is the net forces balanced because it accelerates steadily in a straight line?.
Melissa,
This is something you just plain have to know.
If there is not net force, the momentum does NOT change.
That is Newton's First Law
If there IS a net force, in other words the forces are not balanced, then there is a rate of change of momentum, an ACCELERATION, A, times the mass m . F net = m A
That is Newton's Second Law
If you do not get it, please reply. You just plain have to know it.

Thank you for helping me ! It takes me a little bit longer to grasp concepts, i think now the correct answer is it is unbalanced because it accelerates?
Yes, if balanced it would move along at constant velocity and would not accelerate.
