A body of mass $\displaystyle 10$ kg is projected at an angle of $\displaystyle 45$° with the horizontal. The trajectory of the body is observed to pass through a point $\displaystyle (20, 10)$. If T is the time of flight, then its momentum vector, at time $\displaystyle \mathrm{t}=\frac{\mathrm{T}}{\sqrt{2}}$, is \_\_\_\_.
[Take $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ ]
Official answer
(4)
$\displaystyle 100 \sqrt{2} \hat{i}+(100 \sqrt{2}-200) \hat{j}$
