2001 Ford Focus Grinding engine, then quit

This car has given me very little problems over the years. One day recently, I had to make a very hard left and stomp on the gas to avoid a person driving at me and not looking. The car then sounded like there was something loose in the front end, but continued to drive. The next morning I started it up and it sounded like I was grinding rocks in the engine. It ran for about 40 feet and quit and would not start again.
