A student throws soft balls out of the window at different angles to the horizontal. All soft balls have the same initial speed \( v=10 \sqrt{3} \mathrm{~m} \mathrm{~s}^{-1} \). It turns out that all soft balls landing velocities make angles \( 30^{\circ} \) or greater with the horizontal. Find the height \( h \) (in m) of the window above the ground.
