Let AD and BC be two vertical poles at A and B respectively on a horizontal ground. If $\displaystyle \mathrm{AD}=8 \mathrm{~m}, \mathrm{BC}=11 \mathrm{~m}$ and $\displaystyle \mathrm{AB}=10 \mathrm{~m}$; then the distance (in meters) of a point M on AB from the point A such that $\displaystyle \mathrm{MD}^2+\mathrm{MC}^2$ is minimum is \_\_\_\_.
