Their velocity towards earth increases at that rate, yes. (Your statement seems to imply that the velocity itself is 32 fps, which is not true, except right at the end of the 1st second... but I didn't think that was what you meant).
Garth is right as well.

Umm, isn't the velocity 16 fps at the end of the first second ((start velocity + stop velocity)/2)? Acceleration is 32 fpsps. That is, of course, in the absence of all other forces.

Just to clarify, you're asking if the velocity is 16 fps at the end of the first second because you're using the formula (start V (0 fps) plus end V (32 fps))/2? Read what you wrote again.
End V = (Start V + End V) /2?
No, End V equals End V.
DISTANCE TRAVELLED is 16 feet, if that's what you meant. End V is, well, End V (32 fps).

I guess a DUH is in order here. Sorry.
