Answer 2

this time you are plugging in v = 8 and g = 32. Then you solve for h

Answer 3

yea i got that

Answer 4

but i get stuck solving it

Answer 5

show me what you have so far

Answer 6

\[8=\sqrt{2*32*h}\]

Answer 7

then what do i do?

Answer 8

solve for h

Answer 9

do I multiply 2*32?

Answer 10

yes you do

Answer 11

B?

Answer 12

\[8=\sqrt{2*32*h}\]

\[8=\sqrt{64*h}\]

Answer 13

we need to isolate h

Answer 14

yea thats what i got :)

Answer 15

o ok

Answer 16

\[64=64h^2\]

Answer 17

1?

Answer 18

yes, or you could look at it like
8=8 times h

Answer 19

o ok so its D?

Answer 20

i dont like this problem though

Answer 21

\[8=8\sqrt{h}\]

Answer 22

\[8=\sqrt{64*h}\]

\[8^2=(\sqrt{64*h})^2 \ \text{ Square both sides}\]

\[64=64h\]

Answer 23

:)

Answer 24

i got that :)

Answer 25

you had h squared though

Answer 26

lol i still got it right

Answer 27

i messed up

Answer 28

the setup of the problem isnt dimensionally consistent thought

Answer 29

because squaring or square rooting 1 gives you 1

so in this case, you'll get to the same answer

if you had h^2 = 4, then it'd be a different story

Answer 30

sure it is TylerD

Answer 31

left side is ft/sec

the right side is sqrt( ft/sec^2 * ft) which leads to sqrt( ft^2/sec^2) = ft/sec

Answer 32

oh ok i understand :)

Answer 33

oh ya
