/diy/ - Do It Yourself

I am looking to try and figure out how hard a paintball is hitting an object. I have been looking into force sensors like the one in my pic, but most seem like they are too slow or not good for this application. Is there a better type of sensor or method of testing for this? We have a chronometer, but we need to know how hard it hits and not how fast it goes, and given how we all use different paintballs, we figured calculating from mass would be too much effort for doing it for every shot made. Any ideas or advice on parts?
