An electron was uniformly accelerated from rest to a speed of 2.0 x 10 7m/s.  a.  If the electron traveled 0.10 m while being accelerated what was its acceleration?  

To solve for the acceleration of the electron, we can use the following kinematic equation, which relates acceleration, initial velocity, final velocity, and distance traveled:

\[
v_f^2 = v_i^2 + 2a d
\]

Where:
- \( v_f \) = final velocity = \( 2.0 \times 10^7 \, \text{m/s} \)
- \( v_i \) = initial velocity = 0 (since the electron started from rest)
- \( a \) = acceleration (what we need to find)
- \( d \) = distance traveled = 0.10 m

### Rearranging the equation to solve for acceleration \( a \):

\[
a = \frac{v_f^2 - v_i^2}{2d}
\]

### Substituting the known values:

\[
a = \frac{(2.0 \times 10^7)^2 - 0^2}{2 \times 0.10}
\]

\[
a = \frac{(4.0 \times 10^{14})}{0.20}
\]

\[
a = 2.0 \times 10^{15} \, \text{m/s}^2
\]

### Therefore, the acceleration of the electron is:

\[
a = 2.0 \times 10^{15} \, \text{m/s}^2
\]
