a stone is dropped from a captive balloon at an elevation of 1000ft,. two sec later another stone is projected vertically upward from the ground with a velocity of 248ft per sec. if g is 32ft per sec squared when and where will the stones pass each other?

Best ResponseYou've already chosen the best response.0can u write a equation for the first stone distance travelled by it in t seconds

Best ResponseYou've already chosen the best response.0i know that: \[V _{01}=0 ft/s\] \[V _{02}=248 ft/s\] \[g=32.2 ft/s^2\] \[t _{1}=t _{2}+2\]

Best ResponseYou've already chosen the best response.0So for the first stone distance travelled by it in t seconds is = ut + 1/2 at^2 = 16t^2

Best ResponseYou've already chosen the best response.0now find, for the first stone distance travelled by it in 2 seconds

Best ResponseYou've already chosen the best response.0yeah...wait: so i have these eq. \[Y _{1}=1000Y _{2}\] \[Y _{2}=V _{02}t _{2}1/2(32.2)t _{2}^2\] then i'll substitute and i'll verify my answer later

Best ResponseYou've already chosen the best response.0Let me do it then, for the first stone distance travelled by it in 2 seconds=16*2^2 = 64ft now velocity of it after two seconds = (o^2 + 2*32 *64)^1/2 = 64ft/s

Best ResponseYou've already chosen the best response.0Now,Now, after two seconds, height of the stone after t seonds =100064( ut+1/2 at^2) = 93664t  16t^2

Best ResponseYou've already chosen the best response.0then for the next stone: height of the stone after t seconds = ut + 1/2 at^2 = 248t + 1/2 (32) t^2 =248t  16t^2

Best ResponseYou've already chosen the best response.0Now, when the the stones pass each other , 93664t  16t^2=248t  16t^2 936=312t t=3seconds

Best ResponseYou've already chosen the best response.0so the stone will pass each other at 3+2 seconds = 5 seconds

Best ResponseYou've already chosen the best response.0No, can u find this where will the stones pass each other

Best ResponseYou've already chosen the best response.0(248)(52)\[(248)(52) \frac{ (32.2(52)^2) }{ 2} = 600 ft\] ??

Best ResponseYou've already chosen the best response.0Yep........ 600 ft above the ground
