Re: ~A PHYSICAL CHALLENGE~
[ And now! The last set of pendulums.
The first sword is swinging very fast back and forth. The second is much slower and every two or three passes it lines up with the first sword. The third sword is moving very quickly, much like the first sword -- but in an opposite direction. Every four passes it lines up with the second sword and every six passes it lines up with the first sword.
You could wait and clear all three at once, or clear them one at a time. What do you do? ]
