That was fine since Ionizer was addressing two different topics. Double posting is when two consecutive posts basically say the same thing (except for grammar issues).finagle29 wrote:Hey Ionizer, its considered bad forum etiquette to double post. No hard feelings, but in the future keep in mind that you can edit your post.
Anyway, question: Gary, Barry, Harry, Darry, Larry, Kerry, and Mary have a pendulum each. Gary's is 1m long, Barry's is 2m...etc. up until Mary, who has a 7m long pendulum. They each let go of their pendulums in 1s intervals (so Gary lets go of his at 0s, Barry at 1s, Darry at 2s...up until Mary, at 6s after Gary). When will the periods of the pendulums first coincide?
