Aworker kicks a flat object lying on a roof. the object 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 object attain? assume air resistance is negligible, vi = 15.0 m/s, μk = 0.435, and that the roof makes an angle of θ = 43.5° with the horizontal. (assume the worker is standing at y = 0 when the object is kicked.
