A little physics problem for you.

A truck is traveling west on the highway at 55 miles per hour.

A farmer is selling apples at the train station.

The wind is blowing at 25 knots.

The surface area of the bike trailer is 10 inches square (in base 4).

How far can the truck travel before the bike trailer goes flying out of the back of the truck...

... and hits the man selling apples?

Or, rather, how many pieces of hardware can you lose, and still be able to lash your bike trailer together for a lovely late afternoon bike ride?

15!
