Answer:
Acceleration will be
Explanation:
We have given that car is traveling with speed 34 miles per hour
So initial speed of the car u = 34 miles per hour
After 2 hour speed will be 84 miles per hour
So final speed V = 84 miles per hour
Time = 2 hour
From first equation of motion we know that
So acceleration
