i've got my answer, what have you got?

anonymous · Answer

sorry disconnected ..

anonymous · Answer

i got 490 meters ..I put this 
1/2mv^2 = mgh 
h = 2v^2/g

anonymous · Answer

ops 1/2v^2/g

anonymous · Answer

it is equal to Height ...Am I do this correctly ??

anonymous · Answer

are u there @JFraser ?

jfraser · Answer

that's what i get, also

jfraser · Answer

i used $$V_f^2 = V_i^2 - 2g\Delta x$$

anonymous · Answer

what is value of Vf ??? zero ???

jfraser · Answer

exactly, because it decelerates on the way up, and at the max height, its velocity is zero

i'm leaving to get dinner, so if you have anything else it'll have to wait for someone else

ok ty so much ..I am tagging you in another problem too ..you answer there whenever you 'll free . I am also signing out now .thanks again :)

490 meters is correct answer $$v ^{2}/2g=h$$
