Yes, that is correct, but remember that the initial Kinetic Energy (KEi) is zero in this case.
Once you know KEf, you can calculate V
An electron moves from one plate to another across which there is a potential difference of 2000 V.
a) Find the speed with which the electron
strikes the positive plate.
For this problem, I used the Potential difference equation: (2000)(1.60x10^-19)=3.2E-16=delta PE
I was going to use the equation PEi+KEi=KEf+PEf to find the speed of the electron. Is that right?
