A car traveling at 7.5 m/s accelerates 3.8 m/s2 to reach a speed of 14.0 m/s.
How long does it take for this acceleration
to occur?

1.71s

Explanation:

Acceleration = the change in velocity / the change in time

Or I can write it as

a = V2 - v1

- - -

t

V1 (initial velocity) = 7.5m/s

V2 ( final velocity) = 14.0m/s

a =3.8m/s^-2

Therefore

a= V2 - V1

- - - - - - - -

t

t = V2 - v1

- - - - - - -

a

t = 14 - 7.5

- - - - - -

3.8

t = 1.71s
