Question: One side of the roof of a building slopes up at 30.0°. 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 0.395. 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.
Part A: Determine the maximum height the rock reaches above the point where it was kicked?
I need help to find the maximum height the rock reaches above the point where it was kicked.
