A block of mass $ \text{'}\mathrm{m}\text{'}$ slides along a floor while a force of magnitude $ \text{'}\mathrm{F}\text{'}$ is applied to it at an angle $ \text{'}\mathrm{\theta }\text{'}$ as shown in the figure. The coefficient of kinetic friction is $ \text{'}{\mathrm{\mu }}_{\mathrm{k}}\text{'}$. Then, the block's acceleration $ \text{'}\mathrm{a}\text{'}$ is given by ($ \mathrm{g}$ is the acceleration due to gravity)
