A bullet of mass $\displaystyle 10$ g moving horizontally with a velocity of $\displaystyle 400 \mathrm{~m} \mathrm{~s}^{-1}$ strikes a wooden block of mass $\displaystyle 2$ kg which is suspended by a light inextensible string of length $\displaystyle 5$ m. As a result, the centre of gravity of the block is found to rise a vertical distance of $\displaystyle 10$ cm. The speed of the bullet after it emerges out horizontally from the block will be
Official answer
From NTA’s final answer key for this paper.
(3)
$\displaystyle 120 \mathrm{~m} \mathrm{~s}^{-1}$
