A time dependent force \( \mathrm{F}=6 \mathrm{t} \) acts on a particle of mass \( 1 \mathrm{~kg} \). If the particle starts from rest, the
\( \mathrm{P} \) work done by the force during the first \( 1 \mathrm{sec} \).

W will be :
(1) \( 9 \mathrm{~J} \)
(2) \( 18 \mathrm{~J} \)
(3) \( 4.5 \mathrm{~J} \)
(4) \( 22 \mathrm{~J} \)
