Two similiar barrels A and B with the same radius and mass roll down the same slope starting at the same instant.Barrel A is filled with liqued water, and barrel B is filled with ice of equal mass(Barrel B slightly longer than barrel A to compensate for the slightly larger density of liquid water) which barrel reaches the bottom of the slope first? and why?

well, What does - t stand for in physics ? -t , travel back in time ? -
we go any further, it's important to get a clear idea of what time reversal symmetry really means. At the simplest level, we may think of the laws of physics as equations involving a time variable , and say that they are symmetric under time reversal if given any solution, and making the substitution , we obtain another solution. http://math.ucr.edu/home/baez/time/time.html What does t (and - t) stand for in physics ? only time ?
