A brick has been placed on the roof of a carousel. The roof has a pitch (upward slope) of 20 degrees and the brick is at a radius of 10m from the center of the carousel. The coefficient of static friction between the brick and teh roof is 0.50. What is the maximum number of revolutions per minute at which the carousel may turn without the brick sliding off?
