You want to use a rope to pull a 10-kg box of books up a plane inclined 30∘ above the horizontal. the coefficient of kinetic friction is 0.29. the rope pulls parallel to the incline.
what force do you need to exert on the rope if you want to pull the box with a constant acceleration of 0.50 m/s2 up the plane?
