A spring is used to stop a 59 kg package that is sliding on a horizontal surface. The spring has a constant k = 16 kN/m and is held by cables so that it is initially compressed 110 mm. The package has a velocity of 2.5 m/s in the position shown, and the maximum additional deflection of the spring is s2 = 50 mm. The coefficient of kinetic friction between the package and the surface is uk = 0.20. Determine the total work between positions 1 and 2 if s1 = 600 mm.
