While passing a slower car on the highway, i accelerate uniformly from 12 m/s to 24 m/s in a time of 10.0s. How far do you travel during this time and what is the magnitude of your acceleration

You say that there is uniform acceleration so:

vf-vi=at (final velocity minus initial velocity is equal to acceleration times time)

We know vf, vi, and t so we can solve for acceleration:

24-12=a10

12=10a

a=1.2

That is the acceleration, we will need to integrate with respect to time twice ...

v=⌠a dt

v=at+vi, we know a=1.2m/s^2 and vi=12m/s

v=1.2t+12,

x=⌠1.2t+12 dt

x=1.2t^2/2+12t+xo, we can just let xo=0 for this problem ...

x (t) = 0.6t^2+12t

Now we know that this acceleration lasts for 10 seconds so the distance traveled in that time is:

x (10) = 0.6 (10^2) + 12 (10)

x (10) = 60+120

x (10) = 180 meters
