I think you're trying to find the "force of friction," not "force friction."
To find the force that is caused by the friction between two surfaces, multiply the coefficient of friction by the force that is pressing the two surfaces together.
The coefficient of friction is a characteristic of the two materials that are making contact, and is usually stated in the problem. The force pressing the surfaces together is often the weight of one of the objects. Remember that it is the force acting PERPENDICULAR to the surface that matters. There may also be a force acting parallel to the surface (or you may have to resolve a force into its horizontal and vertical components), but the parallel force does not affect the force of friction between the two surfaces.

Based on the information that you have, you can find it's actual acceleration. That is due to the sum of all the forces on the object. So Ft = Fg - Ff. (I'm assuming there are no other forces on it but gravity and friction. Depeding on the angle that the friction force is acting on, your answer could be more complicated with trig, but i don't have that information to answer the question.
