A 15 kg box is given a shove to the right on a horizontal, rough surface. After the hand loses contact, the box's acceleration (using standard directions) is a = (-1.2 m/s, 0). (a) What are the magnitudes of the normal and weight forces acting on the box? (b) What is the magnitude of the friction force acting on the box? (Hint: you can't use the friction equation for this, because you don't know the coefficient of friction.) (c) What is the coefficient of friction between the box and the surface it is sliding on?
