that means in one second, how far downrange? six kilometers. six kilometers, that's pretty far in one second. that's gonna be... [whistles] way out to here. is it really gonna be up there? - no. - no. it's gonna be where? - it's gonna be underneath. - underneath. how many people be knowing how far underneath? or how many people said, "i don't know." i mean, at six kilometers per second, i don't know that one. come on, how far underneath, gang? - five. - five meters. okay, so it's really gonna be like this. so i gotta dig. i gotta dig a hole. i gotta get that shovel again. now we're gonna dig. notice i don't have to dig so deep? now the path it takes is like this. let's suppose i fire it at 7 1/2 kilometers per second. it's fractions. can you do fractions, 7 1/2 per second? how far downrange at the end of one second? - 7 1/2. - 7 1/2. that's about here, right? is it really gonna be up there? it's gonna be underneath. how far underneath? i still gotta dig. i wonder, maybe there's some speed i could fire whereby i don't be needing a shovel anymore
