... as we might also have derived from the equations of Table 2-1 (particularly Eq. 2-16). The fact that the answer is independent of mass means that the answer to part (b) is identical to that of part (a), that is, v 12.9 m/s . (c) If Ki 0 , then we find Kf = mgh + Ki (where Ki is necessarily posit ...
