We can establish an equation for the electron's position as a function of time.

To convert this to the desired units, we need to use a bunch of unit multipliers:

Strange that your question wants kilometers per second squared instead of the traditional SI unit meters per second squared.

Is ms a millisecond? Or a microsecond?
The other tutor assumed microsecond.
