@DIV$\{$m;s$\}$You are an industrial engineer with a shipping company. As part of the package$-$handling system, a small box with mass $1\mathrm{.}40$ kg is placed against a light spring that is compressed $0\mathrm{.}280$ m$.$ The spring, whose other end is attached to a wall, has force constant k $=45\mathrm{.}0$ N$/$m$.$ The spring and box are released from rest, and the box travels along a horizontal surface for which the coefficient of kinetic friction with the box is k $=0\mathrm{.}300.$ When the box has traveled $0\mathrm{.}280$ m

and the spring has reached its equilibrium length, the box loses contact with the spring.
