A particle having a mass of \( 0.5 \mathrm{~kg} \) is projected under gravity with a speed of \( 98 \mathrm{~m} / \mathrm{s} \) at an angle
\( \mathrm{P} \) of \( 60^{\circ} \). The magnitude of the change of momentum

W of the particle after \( 10 \mathrm{sec} \) is :-
(1) \( 0.5 \mathrm{Ns} \)
(2) \( 49 \mathrm{Ns} \)
(3) \( 98 \mathrm{Ns} \)
(4) \( 490 \mathrm{Ns} \)
