Question: Ferns that eject spores generally do so in pairs, with two spores flying off in opposite directions. The structure from which the spores are launched

Ferns that eject spores generally do so in pairs, with two spores flying off in opposite directions. The structure from which the spores are launched is quite lightweight. If it takes a certain amount of energy to eject each spore, explain how launching the spores in pairs provides for the greatest initial launch speed for each spore.
