$1.$ A box is pushed horizontally through a displacement of $4\mathrm{.}9$ meters by a force of $14\mathrm{.}5$ Newtons. Non$-$conservative forces $($friction$)$ remove $12\mathrm{.}0$ Joules from the system. What is the net work done on the system? Express your result with a single digit of precision.

a$.60\mathrm{.}0$ J

b$.5\mathrm{.}91$ N

c$.59\mathrm{.}1$ J

d$.60\mathrm{.}0$ kgm$/$s$2$
