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 118.0 N at an angle of 18.0° 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. m/s² up the incline (b) The student now starts moving the box up a 10.0° incline, keeping her 118.0 N force directed at 18.0° above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box? m/s² up the Incline
