An electron with an initial velocity 2

An electron with an initial velocity $v_{0}=1.5 \times 10^{5} m/s$ enters a region of length $L=1.00 cm$ where it is electrically accelerated as shown in the figure. It emerges with $v=5.70 \times 10^{6} m/s$. What is its acceleration, assumed constant?

In above equation where you isolate the acceleration you write 2x. where is the initial position? Are you considering initial position 0?

Yes, try to see if you can always place the coordinate system (the starting location) at zero. Makes the math a lot simpler.
