Ariana is accelerating her car at 4.6 m/s^2 it took her 10 seconds to reach this acceleration her starting lost the day was 0 meters per second what was her final velocity

Acceleration of the car driven by Ariana = 4.6 m/s^2

Time taken to reach this acceleration = 10 seconds

Let us assume the final velocity of the car (V2) = x m/s

Initial velocity of the car driven by Ariana (V1) = 0 m/s

Then

Acceleration = (V2 - V1) / Time taken

4.6 = (x - 0) / 10

4.6 = x/10

x = 4.6 * 10 m/s

= 46 m/s

So the final velocity of the car Ariana was driving was 46 meters per second.
