(adsbygoogle = window.adsbygoogle || []).push({}); Kinematics, given only "vi" "vf" and "d"

1. The problem statement, all variables and given/known data

I have a hunch this problem is impossible with the given information.

Using the given information, solve for a and t.

vi = 7.185m/s

vf = -7.185m/s

a = ?

d = 0m

t = ?

2. Relevant equations

Not sure, I think this would be correct.

vf^2 = vi^2 + 2ad (The problem here is obvious when d = 0)

d = 1/2(vi+vf)t (Once again, as far as I can tell, useless when d = 0)

3. The attempt at a solution

Well I can plug and chug the numbers the same as anyone, the problem is that it will always come out to zero.

Thanks in advance guys.
