## Homework Statement

As part of a first order differential equation I need to find [tex]\frac{d}{dt}(mv)[/tex]

where [tex]v=\frac{dy}{dt}[/tex]

## Homework Equations

Product Rule.

## The Attempt at a Solution

[tex]\frac{d}{dt}(m\frac{dy}{dt}) = m*\frac{d}{dt}\frac{dy}{dt} + \frac{dm}{dt}\frac{dy}{dt} = ?? [/tex]

I know I shouldn't have to deal with a second derivative, at least in this equation. Is there a way to simplify the equation first that I'm not seeing?
