A student decides to move a box of books into her dormitory room bypulling on a rope attached to the box. She pulls with a force of128.0 N at an angle of 18.0° above the horizontal. The box has amass of 25.0 kg, and the coefficient of kinetic friction betweenbox and floor is 0.300.
(a) Find the acceleration of the box.
(b) The student now starts moving the box up a 10.0° incline,keeping her 128.0 N force directed at 18.0° above the line of theincline. If the coefficient of friction is unchanged, what is thenew acceleration of the box?
(c) Magnitude?
(d) direction?
