Looks likw a quadratic equation in form of v

#

You have a v^2, a v, and a constant

#

Sorry it was wrong picture, this one is correct

#

here it is also with first lines

So you see how you have v on both sides? That’s why it’s wrong
What you should do is

Set everything on one side (ideally with v^2 as positive)
Rearrange the terms to be v^2 + 2o^2v + 2g(h-h0)
Use quadratic formula to solve for v

#

okay thanks i will try to solve it

#

but what do you mean by v on both sides

#

remote badger but what do you mean by v on both sides

In your final equation you had v = … but in the dots you had a v so v wasn’t isolated

remote badger Sep 30, 2023, 1:09 PM

#

but v0 is different then v

languid mantle Sep 30, 2023, 1:11 PM

#

remote badger

Oh when you added v0^2 you should’ve made it 2v0^2 as you divide by 2

#

Wait 1/2 v0^2

remote badger Sep 30, 2023, 1:13 PM

#

This probably should be correct

#

So where i went wrong?

#

@remote badger physics?

remote badger Sep 30, 2023, 2:46 PM

#

yes

#

i already found the solution

#

when i put v0^2 on the other side of the equation i put it inside the fraction, and you can't do that
