The weight of the block in the drawing is 52.0 . The coefficient of static friction between the block and the vertical wall is 0.550. (a)What minimum magnitude of the force - is required to prevent the block from sliding down the wall? Hint: The static frictional force exerted by the block is directed upward, parallel to the wall. (b) What minimum force is required to start the block moving up the wall:(HInt: The static frictional force is now directed down the walk
