Answer

2.08 m/s

Work Step by Step

In Problem 11a, we used the equation $v = \sqrt {v_{0}^{2} – 2g\Delta h}$ to find the speed of the flake. We can notice that this calculation does not include the mass $m$ of the flake, and so the speed does not depend on it. Therefore the speed will be exactly the same as in Problem 11a, $v$ = 2.08 m/s.
