Question

Ariana is accelerating her car at a rate of 4.6 m/s2 for 10 seconds. Her starting velocity was 0 m/s. What was her final velocity?

Answer 1

v = 46 m/s

Step-by-step explanation:

We have,

Acceleration of Ariana,
`a=4.6\ m/s^2`

Time, t = 10 s

Initial velocity of Ariana, u = 0

It is required to find her final velocity. The rate of change of velocity per unit is equal to acceleration of an object. So,

`a=(v-u)/(t)`

v is final velocity

`v=u+at\\\\v=4.6* 10\\\\v=46\ m/s`

So, her final velocity is 46 m/s.
