should get something near 20 mil
i dont know what i am doing wrong NotLikeThis
did you enter G as 6.67E-11 and the mass of earth right?
yes
did you convert 8 hours into seconds
and then square
yes
yes
to me
to pika
Ummm
oh i see
k i found the error
So, you entered (6.67E-11)* (5.97E24)(83600)^2/4/pi/pi
okay
20300581
yes
there you go
so now you have your r, can solve for v by assuming that the 8 hour trip is constant v across the entire circle
Kepler's law is important
I learned it in hs
it is not complicated
the application of it is not complicated
the math to derive it is a pain in the ass
i got 4428.9 m/s for v
yes
thats right
alright
answer says
answer key says*
oh
it wants it in acceleration
yes
so v^2/r
okay
.97
yeah
you got it
probably not
I did vectors in 4th year, and not real vector shit just simplified non mathy vectors shit
intro to physic usually is kindof
so i should write down this Kepler's Law thing?
it does not go into the math of vectors, uses it for force diagrams
were you not taught it?
no
ummm
well, if this is something you need to hand in, probably need to use an equation they give you
let me think of another way to derive this shit
without kepler
oh i know how you get Kepler
Just derive everything from gauss' laws
ma = GMm/r^2
