It's more than could possibly be provided using fusion, assuming the mass fraction isn't obscenely tilted towards fuel.
That's the beauty of Impellers in Honorverse.
The energy necessary to accel a ship doesn't come from the ship at all. All the ship does is to power the Impeller nodes generating the wedges. The energy for accel comes from hyperspace

I don't recall any sort of quote like this in any of the books I've read. Think you could come up with one?

Yes, and no. Yes as in real life that is the case. No as in for this model we are using Newtonian mechanics, which does not take into account relativity.

Does that mean we can't ever travel at the speed of light?

That is correct.

And wicked pilot? You almost always want to be using relativistic mechanics when dealing with space flight.

You *always* use relativity in space flight. Without taking into account relativity, GPS and satellite communication would be impossible. But for the sake of this discussion board, relavity is slightly too complex. Good ol' Newtonian mechanics will do here.

That's right. The only way to travel at the speed of light is to have no mass. And the only way you can have no mass is to encounter your antimatter self and be converted into gamma ray photons.

So you take the integral of a(t) to find your velocity, and take the integral of v(t) to find the position function s(t).

So, integrating a(t), the velocity should be given by v(t) = 600t + C...

True. However C=0. Remember, at t=0, v=0

Right... well, I'm only taking calculus right now, not calculus with physics. So I'm only interested in the theoretical at the moment

Of course not. Not unless you lose a LOT of weight.

I thought the ship only got energy from hyperspace when in hyperspace using the grav waves.
And you were correct as to what I was looking at, I was mainly trying to get some sort of a power read on Honorverse ships.

Even if we could have mass lightening i wouldnt want it. Imagine if all the subatomic particles in your body had no mass but finite energy. thats infinite speed! you'd explode!
