The Attempt at a Solution

...ughm... kinda don't know how to start...?
but kk.. Fapp=Fgx+Ffs
but.. idk what mui is in Ffs...
so maybe.. Ffs = Fgx going down?

I don't know where to include the speed though...

Sorry, but forum rules state that we need to see an attempt at a solution first before we're allowed to help.
