Aworker kicks a flat rock lying on a roof. the rock slides up the incline 10.0 m to the apex of the roof, and flies off the roof as a projectile. what maximum height (in m) does the rock attain? assume air resistance is negligible, vi = 15.0 m/s, Οk = 0.425, and that the roof makes an angle of θ = 42.0° with the horizontal. (assume the worker is standing at y = 0 when the rock is kicked.)
