A particle projected from ground moves at angle \( 45^{\circ} \) with horizontal one second after projection and speed
\( \mathrm{P} \)
is minimum two seconds after the projection. The angle of projection of particle is [Neglect the effect of
W
air resistance]
(1) \( \tan ^{-1}(3) \)
(2) \( \tan ^{-1}(2) \)
(3) \( \tan ^{-1}(\sqrt{2}) \)
(4) \( \tan ^{-1}(4) \)
