    For 9b, why there is a 1/2 factor in the bracket?
    \dfrac{\mathrm{d}v}{\mathm{d}t} is the rate of change. It's equal to the rate of gain - rate of loss. Write down the information given mathematically and change the subject.

    If c and k are unknown constants then dividing them by two still gives an unknown constant... so I would say it's not necessary to write "c/2" and "k/2".

    I don't think there's enough information given for Q9.
