a lawnmower with a mass of 12 kg is being pushed by a force of 150n horizontally and 40 n down. if the kinetic coefficient of friction between the grass is 0.9, find the force of friction on the lawnmower.
Please explain this as well, I am getting an answer but I don't know.

Friction is mu Fn. The normal force in this case comes from two sources. mg and 40N down. The 150N is not needed for the question.
