    You started a new thread and didn't copy the problem here so I have no idea what you are asking. I searched for "Alonzo" and got "this is a tricky one" but that was answered by Arildno, not Tide.

    Hopefully Tide will know what you are talking about!

    Okay, I found it. (Alonzo is a "damsel"?)

    ? if all of that energy could be used to accelerate a 1000 kg car from rest, what would be the car's final speed?

    The kinetic energy (1/2)m v2 would have to be equal to "all of that energy". Solve for v.

    Thanks, Halls! I just found the problem she was referring too as well.
