## Homework Statement

At some instant in the velocity components of an electron moving between two charged parallel plates are [tex]v_x=1.5x10^5m/s[/tex] and [tex]v_y=3.0x10^3m/s[/tex]. Suppose that the electric field between the plates is given by [tex]\vec{E}=(120N/C)j[/tex].

a)what is the acceleration of the electron?

b)what will be the velocity of the electron after its x coordinate has changed by 2.0cm?

## Homework Equations

[tex]F=ma[/tex]

[tex]\frac{F}{m}=a_y[/tex]

[tex]a_y= \frac{q\vec{E}}{m}[/tex]?

## The Attempt at a Solution

Do I just have to sub in the values for part a?
