OK, I guess I stop jumping on my back bumper to check shocks......... my wife has been after me to lose a few pounds.
Seriously, though, WXman nailed it earlier. Physics, geometry, did I mention physics and the laws of motion and energy, mass, energy cannot be lost, only converted or transferred...... I suppose if he's into meteorology he might know a bit about math......perhaps just a little science.
Mythbusters dropped a piano - the piano weighed 700 pounds and was dropped 50 feet above the roof. They stated that right before impact, the piano would be traveling at 38 mph and in the end have an impact force of 12,000 pounds.
So, if you drop a 10 pound ball 4 feet (48 inches), and it stops in a quarter inch, then the force at the bottom of the fall is
.
2,000 pounds of force on your foot from a 10 pound ball falling 4 feet.
Imagine hitting a pavement dip with a 1,000 trailer tongue - up she goes, down she comes, STOP! The force would be crazy and the leverage of that hitch sticking out back there - more physics (levers)
