okay this is really retarded. but i actually got stuck on this question today. i think it went something like:
a car accelerated from rest and traveled 81 meters in 9 seconds. what was its acceleration?
it was like the simplest Q on the exam. but i cept thinking it must be 9m/s/s because in the first second its going 9, then 18, so on and so on to 81 meters in 9 seconds? but i did the math and got 2 m/s/s. I am still not totally sure. 9 and 2 were both choices. i went with 2. right chocie or wrong?

upon writing this, i think i simply got m/s mixed up with m/s/s
