Load in Motion?

Hello, I am new to the forum and even newer to physics. I am currently researching for the development of a new product at my job and need some help answering some physics related problems. I DO NOT KNOW WHERE TO START!!!

Here is my issue I need to find out if I am carrying a load of X on a trailer and I come to a dead stop (ie hit a brick wall) @ Y mph how much force measured in pounds will be put on the chains holding down my load of X.

That is probally not worded correctly, but that is my best attempt of explianing what I need to figure out. Any help would be appriciated.

THANK YOU!

here the force cannot be calculated or simply force will go up to infinity

F=(m.v-m.u)/t

though mv-mu gives a finite answer as it experiences a sudden stop value of t is so small so F goes to infinity.

So for the events like this we usually calculate only the Momentum

I imagine you colliding with a person who has a relative velocity respect to you, It will give you a real pain...
