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.

Answer 1

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,

Answer 2

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
