F_x = 15.3 "N" F_y = 12.9 "N" F_n = 6.84 "N" (normal force) I'll assume the vector shown with magnitude 20 is the force, and I can't say what the unit m is, although I'll treat it as Newton's, …
Is the actual minimum of a graph still considered a relative
See below. Think that all minima are relative minima but not all minima are global minima. In the case shown, both are relative minima but only at x = 3.219 we get a global minimum.
