I used the conservation of momentum. I have initial momentum of ρi=M*a=70.959 kip*sec
*Vi=51.88mph
*Vf=0 mph
*m1=30,000 lb ======>mass of object
*m2=163 lb ======> mass of 2'x2' 1" plate
*t=1" =====>Thickness of diaphragm plate

I Have an object with a mass of 30,000 lb falling at a height of 90ft. The object is to be stopped by a series of diaphragms spaced out 6" apart. I am using 1" welded plates as diaphrams. I need to find out how many plates it takes to stop the object. I have calculated my potential...
