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?

Respuesta :

Answer:

v = 46 m/s

Explanation:

We have,

Acceleration of Ariana, [tex]a=4.6\ m/s^2[/tex]

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,

[tex]a=\dfrac{v-u}{t}[/tex]

v is final velocity

[tex]v=u+at\\\\v=4.6\times 10\\\\v=46\ m/s[/tex]

So, her final velocity is 46 m/s.
