A student decides to move a box of books into her
Chapter 4, Problem 4.44(choose chapter or problem)
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 80.0 N at an angle of 25.0above the horizontal. The box has a mass of 25.0 kg, and thecoefcient of kinetic friction between box and oor is 0.300. (a) Find the acceleration of the box. (b) The student now starts moving the box up a 10.0incline, keeping her 80.0 N force directed at 25.0above the line of the incline. If the coefcient of friction is unchanged, what is the new acceleration of the box?
