Step : 1
Given- acceleration = 14 meters/second2
It means speed increase by 14 meters/second in every 1 second.
So, In 42 seconds, the speed increases by 14x42 = 588 meters/second .
As the intial speed of car is 12 meters/second and the speed increases by 588 meters/second.
So, final speed = (12+588) meters/second
= 600 meters/second.
