Question

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 = 0.480, and that the roof makes an angle of θ = 43.5° with the horizontal. (Assume the worker is standing at y = 0 when the rock is kicked.)

Answer 1

Just substitute u= 0.480 in this solution.

To get your answer.
