<p>Use Laplace transforms.</p>

<p>Certainly not a dumb question btw. Dif Eq’s can be tricky.</p>

<p>Bump help someone!</p>

<p>What’s your question? If you’re wondering how to go from the circled equation to the one below, than that’s pretty basic integration. I can’t really explain it too well, since you’d ideally just “see” it.</p>

<p>I would take this over to the physics forum’s calculus homework section. That is more of the homework help website.</p>

<p>2f(t) d(f(t))/dt = ?
You can always write 2f(t)d(f(t)) as d(f(t)^2). Just replace f(t) by p to make it more understandable and evident:
2p dp/dt= d(p^2)/dt.</p>

<p>Now, this is valid for any p. So put p=y’ and p=y. See the magic.</p>
