my person question thread is back in business. Here it is. I'm trying to figure out what the Force is of a 910,000 pound aircraft flying at 570 mph. I know that Force= Mass x Acceleration ...
do some reading on net force, and applied force. and, yes, when the plane hits something, you have to assume that there will be an acceleration in the opposite direction from velocity to 0.
yeah, I gots it. I'll assume that it all happens in a second. That gives me an acceleration in the opposite direction of....
570 mph = 821.333 ft/s
821.333 (=difference in speed)/1 second = 821.333 acceleration in opposite direction...
Weight of Jet = Mass x Acceleration(gravity)
Mass of Jet = 28260.87
Mass x Acceleration(1) = Force
A spiderweb made as thick as a fishing net rope could hold back:
DRUM ROLL
23,211,584.78 Pounds of Force
HOLY CRAP! JEHOVAH IS SO AMAZING!
anyone want to check me on this?
I'm not gonna do the math, but thats probably about right. you got the concepts right (after firguring out that when you go from really fast to 0, you are accelerating negatively (decelerating)) and thats half the battle. there's some other stuff involved, such as transfer of momentum.
ok, I did the math and got pretty close to what you got.
this is equivalent to roughly 1,500 large elephants!
