Can you solve these physics riddles? ft Simone Giertz - Part 1/3

I see this video a bit late, but I'll say it's the lighter one. Since g, the acceleration is the same for both, because gravity is proportional with the object's mass and the effects of the force are inversely proportional with the object's mass. But, air friction is something like proportional with the object's square speed, and they both have the same starting speed, so the friction will be the same, but will have more effect on the lighter object's speed, so it will slow it down more, so when it reaches terminal velocity, it will be slower than the heavier object, and thus will experience much less air resistance.
