Yeah, I think I am just going to stick with calculating momentum and be done with this! Thanks everyone for all of the input! :)

So I think what I am getting from the answers that have been posted, is that this is a question that does not give enough information to correctly answer...how would I go about calculating the momentum then? Would it just be 16013.06 lbf times the final velocity of 24.15 ft/s? (386715.399 lbf...

So then final velocity would be... v(f)=0+32.2 (.75)=24.15 ft/s...right? Then where can we go with this?

Hmm, I agree with your statement about the force depending on how easily the object deforms. Do we have to use the elasticity modulus of stainless steel in there somewhere, maybe? I think it is 180 x 10^9 N/m^2 if I looked it up correctly.

Homework Statement Here is my question: A crane is moving a stainless steel coil weighing 497.3 slugs. The crane's cable snaps and the coil falls for 3/4 seconds before hitting the ground. What is the FORCE the coil hits the ground with? Homework Equations F=ma PE=KE?? The...
