Hello,(adsbygoogle = window.adsbygoogle || []).push({});

Running a FEA on a object and need to calculate the deceleration from 5mph to 0mph and 10mph to 0mph . The vehicle weight is 2935lbs. They ran one test and said the vehicle stopped after it crumpled just less than 1". (I assume we can use the distance and velocities to solve the time?? (How long it took to stop from 5-0 in less than 1"))

So if i understand right we want to solve for t not a.

Thank you for your help!!!
