1. The problem statement, all variables and given/known data
An elevator is moving upward at 0.97 m/s when it experiences an acceleration 0.33 m/s2 downward, over a distance of 0.61 m. What will its final velocity be?

2. Relevant equations

Not Sure

3. The attempt at a solution

Welcome to PF!

Hi Leo34005! Welcome to PF!

Use the standard constant acceleration equations.

Show us what you get.

I dont know what to put in

uh??

you have the initial speed, the acceleration, and the distance, and you want the final speed …

which equation(s) do you think that would be?

Leo34005

1st?

tiny-tim

which one is that?

write it out!!

Leo34005

v = u + at

tiny-tim

but you don't have the time!!

Leo34005

v^2 = u^2 + 2as

Is that the right equation, if so what do i plug in?

tiny-tim

if you're not just guessing, you should know what to plug in …

what do you think?​

Forgive me for butting in, but this does not belong in Advanced Physics. This is freshman physics. You might get more help over there.
