A Complex Problem

So my calculus teacher gave me this problem for a take home quiz.

"Ferdbert is driving his race car 324 ft/sec (over 220 mph), when he hits the brakes to pull in for a pit stop. It takes Ferdbert 1093.5 feet to stop his car. His acceleration during the braking period is proportional to time (in seconds) squared. Find the constant of proportion for the acceleration. (That is, find k in the equation a=k*t^2, where a is acceleration and t is time in seconds."

So, Where do I start?
 
I'm not sure if any help can be provided for a "take home quiz" as it may go against the honor code.
 
oh...well i didn't know that. he allows us to work on groups for these problems, but i don't know if that makes a difference. i will delete this topic if necessary.
 
I feel we can remind you that
v=ds/dt and
a=dv/dt

It may make no difference and this may be totally irrelevant.
But I posted this at another site in response to an observation about slowing traffic on the site.
A former graduate student of mine teaches at an area boarding school. She told that when the school became aware of the ‘homework sites’ that school has a new rule: “Post a homework problem, and you go home!”

I have since learned that my daughter’s former prepschool four states away now has a similar rule. It has a strict honor code!

Pka, if that were the case, wouldn't every single person who posts here be breaking the honor code? Remember, this person was honest and said it was for a quiz, but just imagine the number of times we didn't know and answered take home tests and quizes. I can see the point of that school, because they'd rather not even take that chance.
