A student decides to move a box of books into her dormitoryroom by pulling on a rope attached to the box. Shepulls with a force of 80.0 N at an angle of 25.0° above thehorizontal. The box has a mass of 25.0 kg, and the coefficientof kinetic friction between box and floor is 0.300.(a) Find the acceleration of the box. (b) The student nowstarts moving the box up a 10.0° incline, keeping her 80.0 Nforce directed at 25.0° above the line of the incline. Ifthe coefficient of friction is unchanged, what is the newacceleration of the box?
