Have an amazing day and stay hopeful!
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.
