149109 A bullet of mass $25 \mathrm{~g}$ moves horizontally at a speed of $250 \mathrm{~m} / \mathrm{s}$ is fired into a wooden block of mass $1 \mathrm{~kg}$ suspended by a long string. The bullet crosses the block and emerges on the other side. If the centre of the mass of the block rises through a height of $20 \mathrm{~cm}$. The speed of the bullet as it emerges from the block is (take, $\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^{2}$ )
