force on the block from the floor and (b) the block's acceleration. •10 Figure 6-20 shows an initially stationary block of mass $m$ on a floor. A force of magnitude 0.500$mg$ is then applied at upward angle $\theta = 20^\circ$. What is the magnitude of the acceleration of the block across the floor if the friction coef- fcients are (a) $\mu_s = 0.600$ and $\mu_k = 0.500$ and (b) $\mu_s = 0.400$ and $\mu_k = 0.300$?
