Find the acceleration in the x $-$direction, ax $,$ and the normal force, FN$,$ of the moving

block, if there is a force, F $,$ of $100[N]$ applied. The mass, m $,$ of the block, $m=10[kg],$

and the coefficient of friction, ${}_k=0\mathrm{.}3.$ The parts, $($a$),($b$),$ and $($c$)$ below will help

you solve this problem. Make a hand calculation and then use Matlab or Octave for a

computer solution.
