A car has a weight of 156.8N and travels North for 8.9 seconds. What is its final velocity?

OpenStudy (jamesj):

There's not enough information to solve this problem. It could be accelerating, it could be decelerating, it could travel north at 1 m/s or at 1000 m/s or 0.0001 m/s, it could travel north for 8.9 secs and stop exactly at the end. Is there any more information?
