A box of unknown mass is sliding with an initial speed vi = 6.00 m/s across a horizontal frictionless warehouse floor when it encounters a rough section of flooring  d = 2.80 m  long. The coefficient of kinetic friction between the rough section of flooring and the box is 0.100. Using energy considerations, determine the final speed of the box (in m/s) after sliding across the rough section of flooring.
