Step : 1
Given- acceleration = 2 meters/second2
It means speed increase by 2 meters/second in every 1 second.
So, In 41 seconds, the speed increases by 2x41 = 82 meters/second .
As the intial speed of car is 2 meters/second and the speed increases by 82 meters/second.
So, final speed = (2+82) meters/second
= 84 meters/second.
