A) 126 meters/second
B) 126/ 25 meters/second
C) 239/ 25 meters/second
D) 239 meters/second

The linear speed $v$ of a point moving in a circular motion is given by the formula $v = \frac{s}{t}$, where $s$ is the arc length and $t$ is the time. Substituting the given values, $v = \frac{14/25}{9} = \frac{14}{25} \times \frac{1}{9} = \frac{14}{225} = \frac{126}{225} = \frac{126}{25}$ meters/second.
