One side of the roof of a building slopes up at 38.0°. a roofer kicks a round, flat rock that has been thrown onto the roof by a neighborhood child. the rock slides straight up the incline with an initial speed of 15.0 m/s. the coefficient of kinetic friction between the rock and the roof is 0.390. the rock slides 10.0 m up the roof to its peak. it crosses the ridge and goes into free fall, following a parabolic trajectory above the far side of the roof, with negligible air resistance. determine the maximum height the rock reaches above the point where it was kicked.
