surface. The spring has a constant k = 20 kN/m and is held by cables so
that it is initially compressed 120 mm. Knowing that the package has a
velocity of 2.5 m/s in the position shown and that the maximum additional
deflection of the spring is 40 mm, determine (a) the coefficient of kinetic
friction between the package and the surface, (b) the velocity of the package
as it passes again through the position shown.
