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?

Verified Answer :

if the starting velocity was 0, all you have to do is multiply the acceleration to the time, aka 4.6x10
so 4.6x10 would be
46

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 = \(4.6\ m/s^2\)

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,
