\( 216 \mathrm{~kg} \) spherical object with density \( 2 \mathrm{~g} / \mathrm{cm}^{3} \) sinks in the liquid with density \( 1 \mathrm{~g} / \mathrm{cm}^{3} \) and viscisity \( \eta=10 / 3 \mathrm{n} . \mathrm{s} / \mathrm{m}^{2} \). What is the ultimate velocity in terms of \( \mathrm{m} / \mathrm{s} \). (Assume \( \pi=3 \) and \( g=10 \) !!!!!!)

Answer To find the ultimate velocity of the object, we need to consider the forces acting on the object as it sinks through the liquid. The main force
