I'm going to hold a dog protection tournament. I'd like to give the audience information about the force of the impact of the running dog when it hit(attacks) the decoy on a huge screen. I'm a software developer student so I have the neccesary skills to development the software/electronics for the project. However, i'm not a physicist and I'm getting quite confused looking on all the formulas that I find online.
My question is therefore. Is it possible to calculate the force of impact in kilograms of the dog hitting the decoy (seen as a stationary object)?
As an example how should I calculate the force if say the dog weights 40kg and is running at a speed of 30 km/t?
