Question

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?

Answer 1

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

Answer 2

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,
