A body of mass $40\,kg$ resting on rough horizontal surface is subjected to a force $P$ which is just enough to start the motion of the body. If $\mu_{ s }=5, \mu_{ x }=0.4$, $g =10\,m / s ^2$ and the force $P$ is continuously applied on the body, then the acceleration of the body is $.........m/s^{2}$
