Ariana is accelerating her car at 4.6 m/s2. it took her 10 seconds to reach this acceleration. her starting velocity was 0 m/s.

what was her final velocity?

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,

i would say
