please update your answer to include the notion that stopping is not a requirement. thanks!

Note that stopping is not a requirement -- just that after time $T$, the vehicle has not travelled past $D$, using minimal constant deceleration $a$. Stopping is an option if just slowing doesn't work out.

Meant to say...actually I think it may be working, but wanted to see if I was missing something...thanks!

Yes the deceleration is due to friction. Actually I think $a=2\frac{vt-d}{t^2}$ combined with the check for non-negative final velocity (and if it is negative then just apply the deceleration that stops right at $d$). But I'm still having issues getting the problem judged as correct so I wanted to see if this is a correct approach or if I was missing something.
