An object of mass m is at rest at the top of a smooth slope of height h and length L. The coefficient of kinetic friction between the object and the surface, μk, is small enough that the object will slide down the slope if given a very small push to get it started. Find an expression for the object's speed at the bottom of the slope.

Express your answer in terms of the variables m, μk, L, h, and appropriate constants.

So the problem ask to find the expression for the objects speed at the bottom of the slope and express it in the term variables in your problem. Base on my calculation the equation might be speed = square root of (2g (H-LuK)). I hope you are satisfied with my answer
