Question 30

Two autonomous runway inspection vehicles pass the same painted line at the same instant and travel in the same direction on parallel routes.

Vehicle A has a velocity of 1.0 m/s as it passes the line. During the next 2.0 s, its velocity increases uniformly to 7.0 m/s. It then travels at 7.0 m/s for a further 4.0 s.

Vehicle B travels at a constant velocity for the whole time.

After a total time of 6.0 s, Vehicle B is 12 m behind Vehicle A.

What is the constant velocity of Vehicle B?
