How do I solve this diff. eq problem?

[gplanet]

I'm trying to solve this problem:

y'' + t(y')^2 = 0

i got up to:

v' + tv^2 = 0

but i don't know what to do now! any help? thank you in advance

This was so two quarters ago.

Translation: I don't remember anymore

Somebody tell me where the V came from!

Are we magically supposed to assume that y is position and V is velocity? Tell us a bit about it...

If you could quote the entire problem, it would be helpful.

Means that acceleration is being expressed as a function of position, or vice versa... neither are known. Ugh.

Just remember F = ma and you can't push a rope.

sorry for not being clearer

v = y'

i just substituted it

it has nothing to do with physics
