160790 A body of mass $40 \mathrm{~kg}$ resting on rough horizontal surface is subjected to a force $P$ which is just enough to start the motion of the body. If $\mu_s=0.5$, $\mu_{\mathrm{k}}=0.4, \mathrm{~g}=10 \mathrm{~m} / \mathrm{s}^2$ and the force $\mathrm{P}$ is continuously applied on the body, then the acceleration of the body is
