I really don't know where to find the acceleration of the object in this question. When you push a 1.8 kg book resting on a tabletop, it takes 2.25 N to start the book sliding. Hwat is the coefficient of static fraction? Any help would be greatly appreciated, I have already done the force diagram and equations, found Fg and Fn, I just don't know how you would find the acceleration of the object. Thank You!
