Keep something moving for a full fifteen seconds without ever letting it break 3 m/s. Slow is easy. Slow and never stopping is not.
A body labelled “pendulum” must still be moving faster than 0.2 m/s at the end, and no body may exceed 3 m/s at any point.
Runs for 15 simulated seconds. Everyone who solves it is ranked by fewest forces.
Solving pays 50 Atoms, and finishing high pays more once the contest closes. The studio reports how the scene was built; that never decides whether an entry counts, it only decides whether a person looks at it.
Nobody has solved it yet. The first to do so earns half again on top.
