The ball is moving at 55mph and it is not directly connected to the truck so when it suddenly stops the ball will want to move foreword with a force of 55mph.

So if the truck was moving at 55mph then stopped on the line that is a negative acceleration from 55mph to 0mph. The ball will be shot at a positive acceleration from 0mph to 55mph. If these two accelerations occur at the same moment then the ball will not travel anywhere.
