you fire a little higher speed, splasharoony down here. how fast would you have to fire that cannonball, no splash? check the neighbor, see if the neighbor know. how many say it's 8 kilometers per second? can i have a show of hands? yeah, my people, my people. 8 kilometers per second will do it. 1 second later, if you're 8 kilometers away, you'll be just as far off the ground as you were here, 'cause don't forget this distance above to that straight line is a 5 meter drop, which tells us how satellites operate. newton talked about that years ago. newton says consider a mountain high enough to be, not above gravity, a lot of people think above gravity, no, no, no, no, to be above the drag of the atmosphere. put a cannon on there and fire that cannonball and guess how fast it'll orbit. 8 kilometers per second... what you do is you orbit all the way around-- you're falling all the time, fall, fall, fall without ever hitting the ground. so that speed will put you in orbit. so next time you're watching the television set and you see they're gon
