Are these free-body diagrams correct (mass-spring-damper system)?

    Problem: Write the equations as a set of two, second-order ordinary differential equations.

    You post a picture of the question and you post a picture of your answer. Your question is: does it look correct?
    Well, what if it does? Which parts are you confident about, which parts are somewhat less certain in your opinion?
