$($Bonus $20$ points$)$ A uniform $50-$kg box rests on a horizontal surface for which the coefficient of kinetic friction is $0\mathrm{.}2.$d$.(10$ points$)$ Determine the acceleration if a force of P $=600$ N is applied tothe box.e$.(10$ points$)$ Determine the $\text{'}$x$\text{'}$ where the normal force is acting on the box.If x is more than the half size of the box, then the sliding motion would not be maintained $($box
