create a small class or structure to hold your sum, hdistance and vdistance, and then have a vector containing type of your structure.
Do it the same way you got the data from the file.

then you can populate them in your loop.

{
hdistance=(VO[0]*sum*sin(radians))-(4.905*(sum*sum));
vdistance=VO[0]*sum*cos(radians);
sum=sum+DT[0];
HDISTANCE.push_back(hdistance);
VDISTANCE.push_back(vdistance);
SUM.push_back(sum);
