A worker 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,
μk = 0.415,
and that the roof makes an angle of
θ = 39.5°
with the horizontal. (Assume the worker is standing at
y = 0
when the rock is kicked.)
