As shown in the figure, a particle of mass $\displaystyle 10$ kg is placed at a point A. When the particle is slightly displaced to its right, it starts moving and reaches the point B . The speed of the particle at B is $\displaystyle x \mathrm{~m} / \mathrm{s}$.
(Take $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ )
The value of ' $\displaystyle x$ ' to the nearest integer is \_\_\_\_.Official answer
10
