A 50.0 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 1.75 m/s and that it stops in 2.25 s with uniform acceleration. What magnitude force does friction exert on this box?

Answer:
38.9 N
Explanation:
calculate acceleration with the help of Newton's kinematics equation as initial and final velocities are given ,then use second law of motion equation to calculate force due to friction ...
