Am I reading it wrong? or am I writing to much into the equation?
It looks like you're trying to intuit the situation without even the vaguest understanding of it. As stingc has pointed out, the dimensions (or units) aren't even correct.

So, to answer your question (in case it's not clear, already), no. Velocity times momentum does not equal acceleration.

The derivative of momentum with respect to time divided by mass equals acceleration. Does this clear things up?
