The projectile motion of a particle of mass $\displaystyle 5$ g is shown in the figure.
The initial velocity of the particle is $\displaystyle 5 \sqrt{2} \mathrm{~ms}^{-1}$ and the air resistance is assumed to be negligible. The magnitude of the change in momentum between the points A and B is $\displaystyle x \times 10^{-2} \mathrm{kgms}^{-1}$. The value of $\displaystyle x$, to the nearest integer, is \_\_\_\_.
