| The most straightforward distance to find is finding the maximum possible distance a harpoon can reach. This will occur when the block is dropped over the greatest distance (from the roof) and launched from the highest elevation (also from the roof). So, let's work with this first. | The most straightforward distance to find is finding the maximum possible distance a harpoon can reach.
