Question

New post cause I'm still at a loss: ODE Question
A mass weighing 2lb stretches a spring 1.2in. The mass is pushed 6in. downward and released. The motion takes place in a medium with damping constant 1lb s/ft. Find the position of the mass at any time t≥0

@hartnn ,@Hero

Answer 3

@hero dont know if you know ode though

Answer 4

@zzr0ck3r

Answer 5

not good at this stuff

Answer 6

darn ok

Answer 7

I keep forgetting that

Answer 8

:(

Answer 9

is this really an ODE? looks like a regular physics problem to me

Answer 10

looks like Chinese to me.

Answer 11

it's an ode problem we meed to solve this second order \[my''+\gamma y'+ky=0\]

Answer 12

wait nin, can you find the spring constant?

Answer 13

I think this is pretty easy

Answer 14

well that is^^^

Answer 15

of course, very easily

Answer 16

lol I'm getting 20 for my spring constant

Answer 17

k = F/d

Answer 18

I have a whole question devoted to this already alctually, but dan and I got nowhere

Answer 19

right nin

Answer 20

because he doesn't know it yet

Answer 21

ganesh to the rescue!

Answer 23

he's one of the best here LAUGHING OUT LOUD!

Answer 24

oh, YAY I'm saved

Answer 25

Do you want all my work? I'm getting an imaginary r and I have no clue what arctan(-2)=?
