The correct answer to this question is 46 m/s.
CALCULATION:
As per the question, the initial velocity of the car u = 0 m/s.
The acceleration of the car is given as a =
The time taken by the car t = 10 seconds.
We are asked to calculate the final velocity of the car.
From equation of kinematics, we know that-
v = u + at
= 0 + 4.6 × 10 m/s
= 46 m/s. [ans]
Hence, the final velocity of Ariana's car is 46 m/s,
