Answer
$0.16\;J/K$
Work Step by Step
The newly “unavailable” kinetic energy is the heat term in the entropy calculation. Kinetic energy was transformed into thermal energy, which increases the universe’s entropy.
$$\Delta S=\frac{Q}{T}=\frac{0.5mv^2}{T}$$
$$=\frac{0.5(5.8kg)(4.0m/s)^2}{ 293K}$$
$$=0.16\;J/K$$
