A decorative snowman with mass m = 15kg slides down a roof that is inclined at an angle of 30 º from the horizontal. The snowman slides a distance of 6.0m down the roof and off the edge, located 8.0m above the ground. The coefficient of kinetic friction for the roof is 0.20. What is the horizontal distance from the edge of the roof to the point where the snowman hits the ground?
