    I'm doing some questions from my book and I have no idea how to do this one so if someone could help that would be great

    A Barge of mass 2x10^5 is being towed, with a force of 2.5x10^4N, in a straight line with an acceleration of 0.006ms^-2. Calculate the magnitude of the resisting force provided by the water.

    the answer is 1.3x10^4

    You can calculate the total unbalanced force using F = ma, if the unbalanced force is towing force + (- resisting force), how could you find the resisting force?
