we only care about velocity relative to the shuttle.
foam and shuttle start with same velocity up. relative velocity of foam from shuttle is zero. so, the more the foam decelerates due to air, the _greater_ its velocity relative to the shuttle. ice decelerates less and thus has a lower relative velocity, even though it has a higher absolute velocity.
