A nozzle is so shaped that the average flow velocity changes linearly from $1.5 \mathrm{~m} / \mathrm{s}$ at the beginning to $15 \mathrm{~m} / \mathrm{s}$ at its end in a distance of $0.375 \mathrm{~m}$. The magnitude of the convective acceleration (in $\mathrm{m} / \mathrm{s}^{2}$ ) at the end of the nozzle is
