N2 - We have investigated both the longitudinal wave velocity in a 2 dimensional (2D) model system and the propagation velocity of a cooperative motion found in our previous papers. The longitudinal wave velocity is about 12 σ1/τ, but the propagation velocity of a cooperative motion becomes near 3 σ1/τ. And the longitudinal wave velocity increases slightly according to increasing the temperature. On the other hand, the propagation velocity of a cooperative motion decreases according to increasing the temperature. These results indicate certainly different physical origins for these atomic motions.
