Ok, so I am doing a typical momentum problem with a varying mass (here dm/dt > 0). I am also taking into account air resistance (stoke's law essentially). After some manipulations I basically get:(adsbygoogle = window.adsbygoogle || []).push({});

6πnRv - mg(1 - p(water)/p(object)) = m (d/dt(v)) + v (d/dt(m))

I know I need to separate the variables but I am lost on how. Thank you for the assistance!
