A block is placed on a slope as depicted in the graph. The static and dynamic coefficients of friction between the block and plane are 0.25 and 0.2. respectively. A) What is the steepest angle e for which the block will remain stationary? B) if e is just greater than the critical value, what is the acceleration of the block down the slope once it has started sliding?
