Nov 6 comment How do I find minimum constant deceleration so that object does not pass distance d in time t? please update your answer to include the notion that stopping is not a requirement. thanks! Nov 3 comment How do I find minimum constant deceleration so that object does not pass distance d in time t? 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. Nov 2 comment How do I find minimum constant deceleration so that object does not pass distance d in time t? Meant to say...actually I think it may be working, but wanted to see if I was missing something...thanks! Nov 2 comment How do I find minimum constant deceleration so that object does not pass distance d in time t? 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.
