Problem

obstruction (3)
target
Question: You need to fire a rocket from somewhere along the ground, past the obstruction,
to hit the target. You may assume that the rocket travels in a straight line. Find x such
that your trajectory length L is as short as possible (hence your rocket needs as little fuel as
possible). Once you have done so, cut out a piece of masking tape the exact length of this
predicted shortest path.
