I believe that this calculator generates answers assuming that the only force acting on a falling object after it has encountered a stopping surface is the force of the stopping surface. The calculator needs to factor in gravity throughout the whole fall. Would someone else please verify?
Click Mechanics, work-energy principle, and then impact force of falling object, and "Since you know velocity, mass, and kinetic energy, can you predict the force of impact?"
m=50kg, h=10m, d=5m
stopping force should be about 1480N, but the calculator is saying 980N.

Read the little note at the bottom of that page.

I didn't take time to read that disclaimer carefully. Thanks for the quick answer!
