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 172 N at an angle of 29.0° above the horizontal. The box has a mass of 24.0 kg, and the coefficient of kinetic friction between box and floor is 0.300.
(a) Find the acceleration of the box.
m/s2
(b) The student now starts moving the box up a 10.0° incline, keeping her 172 N force directed at 29.0° above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box?
m/s2, up the incline
