A student decides to move a box of books into her dormitory room bypulling on a rope attached to the box. She pulls with a force of110.0 N at an angle of 23.0° above thehorizontal. 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 pulls the moving box up a 10.0° incline,keeping her 110.0 N force directed at23.0° above the line of the incline. If the coefficient of friction isunchanged, what is the new acceleration of the box?
