0A force acts on a \( 3.0 \mathrm{~g} \) particle in such a way that the
\( \mathrm{P} \)
position of the particle as a function of time is given by \( x=3 t-4 t^{2}+t^{3} \). Where \( x \) is in metre and \( t \) in second.

The work done during the first \( 4 \mathrm{~s} \) is
(1) \( 570 \mathrm{~mJ} \)
(2) \( 450 \mathrm{~mJ} \)
(3) \( 490 \mathrm{~mJ} \)
(4) \( 528 \mathrm{~mJ} \)
