Question

A body of mass 10 kg is projected at an angle of $45^{\circ}$ with the horizontal. The trajectory of the body is observed to pass through a point (20, 10). If T is the time of flight, then its momentum vector, at time $\mathrm{t}=\frac{\mathrm{R}}{\sqrt{2}}$, is__________ [Take g = $\left.10 \mathrm{~m} / \mathrm{s}^2\right]$

Select the correct option:

$100 \hat{i}+(100 \sqrt{2}-200) \hat{j}$

$100 \sqrt{2} \hat{i}+(100 \sqrt{2}-200 \sqrt{2}) \hat{j}$

$100 \hat{i}+(100-200 \sqrt{2}) \hat{j}$

$100 \sqrt{2} \hat{i}+(100 \sqrt{2}-200) \hat{j}$
