Why the following situation impossible? A shopper pushing a cart through a market follows directions to the canned goods and moves through a displacement 8.001 m down one aisle. He then makes a 90.0 turn and moves 3.00 m along the y axis. He then makes another 90.0 turn and moves 4.00 m along the x axis. Every shopper who follows these directions correctly ends up 5.00 m from the starting point.
