Kinematics, given only vi vf and d

[Omnistegan]

Kinematics, given only "vi" "vf" and "d"

Homework Statement

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 = ?

Homework 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)

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.

Are you sure d=0? What is the original problem statement, word for word?

 

[Omnistegan]

d certainly is 0.
The question is exactly as I have above.
My impression was that this question resembled the vertical component of a projectile motion question. Up and back down, 0 displacement.

My opinion is that it can't be solved with only that information. Perhaps we're thinking too hard though

It would seem to me that the question has been misinterpreted, or miswritten. I certainly don't see a way to solve it with the current data.
