solve this

Galileo wants you to create a proportionality:

"the spaces described by a body falling from rest wit a uniformly accelerated motion are to each other as te squares of the time intervals employed in traversing these distances"

in first second it falls 5 meters

how long until its gone 100

Then he can ask us himself.

is it 42?

Posted by Orbax on May-05-2005 01:31:

Im pretty sure I already got it.

but the next problem is dropping a stone from that distance up along vertical axis but using 10m/s/s as acceleration constant. but then asks where stone will be after 1,2,3,4,5 seconds...im pretty sure it hits 4ish, dunno why he asked 5

ugh...sounds like derivatives

waaaaaaaaaaaay too hammered to even read it heheheh

its actually easy...was trying to apply way too much other stuff to it

d = vo*t +1/2 a*t^2

Do your own homework!

i love physics.

Posted by Orbax on May-05-2005 05:25:

since was a single axis was d=.5(9.8)T^2

ended up bein cake...didnt think they were doing it as easy as they did hehe

I enjoy physics but I hate all that shit about motion and so on.

That's the answer to life, the universe and everything. And the question is "what is six times nine."

7 seconds?

EDIT:

s = ut + 0.5at^2 =>
100 = 0 + 0.5*5t^2 =>
100 = 2.5t^2 [divide by 2.5]
40 = t^ [square root]
6.32 = t

Ta da.
