A body of mass \( 5 \mathrm{~kg} \) starts from the origin with an
\( \mathrm{P} \)
initial velocity \( \vec{u}=(30 \hat{i}+40 \hat{j}) \mathrm{m} / \mathrm{s} \). If a constant force \( (-6 \hat{i}-5 \hat{j}) \mathrm{N} \) acts on the body, the time in which the \( y \) component of the velocity becomes zero, is
(1) \( 5 \mathrm{~s} \)
(2) \( 20 \mathrm{~s} \)
(3) \( 40 \mathrm{~s} \)
(4) \( 80 \mathrm{~s} \)
