Piles of snow on slippery roofs can become dangerous projectiles as they melt. Think a chunk of snow at the ridge of a roof with a pitch of 30 degrees. Because the snows begin to melt it will eventually slip. Assuming that the distance from the chunk to the edge of the roof is 5.0 m and that the coefficient of kinetic friction is 0.20, calculate the speed of the snow chunk when it slides off the roof. (Note: A free body diagram is needed for this question.)
