A rectangular wooden block with mass m $=2$ kg$,$ height h $=20$ cm$,$ and width w $=10$ cm isplaced on an inclined plane. The coefficient of static friction between the block and the inclinedplane is Mew s$=0\mathrm{.}4\mathrm{.}1.$ Calculate the critical angle slide at which the block will begin to slide down the incline$\mathrm{.}2.$ Calculate the critical angle topple at which the block will begin to topple$\mathrm{.}3.$ Determine whether the block will slide first or topple first as the incline angle is gradually increased. Justify your answer with calculations.
