Solution to the symbolic problem pitting drag against friction,written below:

A light box sits at the edge of a table near a fan which blows wind onto it.  When the fan on its lowest setting, the wind it generates is cannot push the box off of the table.  However, at its highest setting, the wind will push the box off of the table.  This intrigues you: what is the minimum speed that the wind has to blow on the box in order for it to fall off?
