An athlet throws a shotput of mass $25 \mathrm{~kg}$ with an initial speed of $4 \mathrm{~ms}^{-1}$ at an angle of $45^{\circ}$ with the horizontal from a height of $2 \mathrm{~m}$ above the ground. Assuming air resistance to be negligible, the kinetic energy of the shotput when it just touches the ground is ____ $\left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)$
