In the figure, blocks $$A$$ and $$B$$ have weights of $$47\mathrm{N}$$ and $$22\mathrm{N}$$, respectively. (a) Determine the minimum weight of block $$C$$ to keep $$A$$ from sliding if $${?}_s$$ between $$A$$ and the table is $$0.21$$. (b) Block $$C$$ suddenly is lifted off $$A$$. What is the acceleration of block $$A$$ if $${?}_k$$ between $$A$$ and the table is $$0.14$$ ? (a) Number Units (b) Number Units
