Admittedly, I'm not a physics guy and the question I have is probably pretty simple. However, I don't know the answer and need some expert assistance. Long story short is that my dog was struck by a vehicle last night and I believe the person was travelling well above the posted speed limit. He'll fine and the lady did stop to say she was sorry.
Question: What is the formula for determining the speed of the impacting vehicle?
Any information, as 'dumbed down' (laymans terms) as you can make it, would be VERY helpful for me.
The dog is roughly 24 inches high at the shoulder and roughly 50 pounds and was in motion at the time of being struck. The drag/skid marks from the DOG (not the car- ABS breaks and all) is roughly 20 feet or 7 long strides for me. There's also a positive (uphill) slope involved, but very minimal.
