Question

4. A 1.2 kg block of mass is placed on an inclined plane that has a slope of 30° with respect to the horizontal, and the block of mass is released. A friction force Fk = 2.0 N acts on the block as it slides down the incline. Find the acceleration of the block down the incline.

I know that you do a=f/m which equals 1.7 but I don't know if its positive or negative 1.7?
