Road Accident in COSMOSworks

Hi all
We design Coaches structure and I've to analyse its strength duringdifferetnt type of road accident.
Upto I know "Drop test" is suitable for that but I dont haveCOSMOSWorks Proffesional.
So for the time being (before upgradation) I get the required force(by which it hit the any other object) by Newton's second Law ofmotion (F=ma) assuming final velocity zero and giving andrestrained bottom of the vehical.
Is anyone know better methode rather upgradation.
