<s>[INST] The point P represents a particle moving on a straight line with a constant acceleration of 3 m/s^2 , and the point Q represents another particle moving on the same straight line with a constant acceleration of 2 m/s^2 . When the points P and Q are at the same place on the straight line , the absolute value of the difference in their velocities is 5 m/s . If P and Q meet again at some later time, what is the absolute value of the relative velocity at which they pass each other at that meeting?[/INST]
