This is a long question that needs to be fully done on paper, scanned and uploaded. Also type in the answer of (a) in the space provided.

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 11 N at an angle of 87 degrees relative to the horizontal. The box has a mass of 14 kg and the coefficient of kinetic friction between the floor and box is 0.83.

Calculate the acceleration of the box.
The student now starts moving the box up a 17 degree incline, keeping her 11 N force at 87 degree above the line of the incline. If the coefficient friction is still 83, calculate the new acceleration.
