A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 128.0 N at an angle of 17.0° above the horizontal. The box has a mass of 25.0 kg, and the coefficient of kinetic friction between box and floor is 0.300. (a) Find the acceleration of the box (b) The student now starts moving the box up a 10.0° incline, keeping her 128.0 N force directed at 17.0° above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box?
