|title: Bulldozer on Moving sheet|
aka: Crossing the River
Toy bulldozer moves at a constant speed across a sheet of plastic on wheels. The velocity of the bulldozer relative to the earth is seen as the vector addition of its velocity and that of the sheet.
What direction do you aim the bulldozer so that it moves directly across a moving sheet?
