[Wholly Cow]

I am trying to find a simple table for g force but i am having a hard time finding something that can be explained in laymans terms.
An object (with a weight of 50kg) is dropped straight down 3.81 Meters
(which is equal to 12.5 feet, or 1 story) to solid concrete resulting in a
stopping distance of 1cm. How many gs of force does the object
“experience”? Can you help me?
