The equations of motion of a projectile are given by
\( \mathrm{P} \)
\( x=36 t \mathrm{~m} \) and \( 2 y=96 t-9.8 t^{2} \mathrm{~m} \). The angle of
W
projection is
(1) \( \sin ^{-1}\left(\frac{4}{5}\right) \)
(2) \( \sin ^{-1}\left(\frac{3}{5}\right) \)
(3) \( \sin ^{-1}\left(\frac{4}{3}\right) \)
(4) \( \sin ^{-1}\left(\frac{3}{4}\right) \)
