A student decides to move a 25.0 kg 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 25.0° above the horizontal and the coefficient of kinetic friction between box and floor is 0.300. What is the magnitude of the acceleration of the box?
(A) If the student let go the box up a 10.0° inclined plane, keeping her 80.0 N force directed at 25.0° above the line of the incline. What is the maximum height reached by the box?
(B) After the box slides back on the ramp, what will be its maximum velocity at the bottom?
1) Make a list of the given variables
2) Draw a FBD with the forces acting on the box.
3) Show your calculations.
