This is a long question that needs to be fully done onpaper, 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 roomby pulling on a rope attached to the box. She pulls with a force of11 N at an angle of 87 degrees relative to the horizontal. The boxhas a mass of 14 kg and the coefficient of kinetic friction betweenthe 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 newacceleration.
