In a mail-sorting facility, a 2.50-kg package slides down an inclined plane that makes an angle of 20.0° with the horizontal. The package has an initial speed of 2.00 m/s at the top of the incline, and it slides a distance of 12.0 m.
What must the coefficient of kinetic friction between the package and the inclined plane be so that the package reaches the bottom with no speed?
