Initially m and m' are at rest and at the same height. The planes are perpendicular. Find the minimal distance that separates m and m'.
Homework Equations
The Attempt at a Solution
Well the distance that separates them is the length of the vector that describes m 's position relative to m'. But then I fail to find any idea on how to get to that vector.
Thanks for your help.
