A 10.0 kg box is accelerating down a frictionless incline as shown. What are the magnitudes of the parallel and perpendicular components of the gravitational force acting on the box?

A50.0-n box is sliding on a rough horizontal floor, and the only horizontal force acting on it is friction. you observe that at one instant the box is sliding to the right at and that it stops in 2.25 s with uniform acceleration. what magnitude force does friction exert on this box
