You just landed on the planet Olympus IV, famous for its sports competitions. It's a light planet: the average density is one quarter of the Earths average density. It's also a large planet: the diameter is the double of the Earths diameter. The Olympians are giving a high jump competition, and one crew member takes part. You know that on Earth he jumps 1.98 meters. The record at Olympus IV is 3.86 meters. Should you bet your salary on him winning the competition ?

Isn't that "Does S=s?", rather than V?

In any event, that's a definite question.  One would think that with lower gravity, one would be able to reach a greater initial velocity, and so even beat the old record.
