1. Homework Statement
physicscut.jpg

xi=2.0
ti=0

i know the acceleration is -2.0 @ t=3 using the change v/ change t (rise over run)
the vx@ t=3 is two
and t=3
so i need to find the position of x
so i pluged in the formula x= xi+vt+1/2vt2 and I get 11..but i'm way off

2. Homework Equations

see above

3. The Attempt at a Solution

tried a few times working from going from the initial x all the way and I get 11 again.

Am I not entering in the sig figs right or am i way off?

I just found this forum and love it!

That equation is for constant acceleration only.
The acceleration changes in this problem, so that equation will not work.

How do you get displacement from velocity in general?
