A box of mass $0\mathrm{.}5$kg slides down a rough ramp with an initial speed of $2\mathrm{.}0$ m$/$s.

 

 $$ The ramp is inclined at an angle of $30$ above the horizontal. The box slides a distance of $1\mathrm{.}5$ m and comes to rest before reaching the bottom of the ramp. The energy dissipated as the box slides to a stop is ?
