Why will my 97 mustang not start, it will turn over but wont start?

What is your question?

On the way home from buy my stang in another town, me and my girlfriend were coming into our town going over am over pass, when we hit some black ice and started to slide. I almost got it under control when we hit another spot of black ice, this time we ended up hit the cement barrior stopping us from going off the side. Then we got hit by another car on the driver side just behind the door. After the other vehicle hit us the stang would not start but because I have a keyless start it tried to start but just kept turning over. after having it towed home the car wont even turn over now. I am currently charging the car battery as a just incase something got left on over the past few days. Any suggestions and ideas are genuinely welcome.

How long has your 1997 Ford Mustang had this problem?
