Where are the solutions to the warm-up exercises of the drude model?

I just wanted to look at the solutions to the warm-up exercises of the drude model, but they are not there. Even if I look at the page with the solutions to the drude model (Solutions for Drude model exercises - Open Solid State Notes) the warm-up exercises are not there. Where can I find these solutions?

  2. Yes
  3. Because forces add in the equations of motion
