Power supplied to a particle of mass \( 2 \mathrm{~kg} \) varies with time as \( P=3 t^{2} / 2 \mathrm{~W} \). Here \( t \) is in second. If the velocity of particle at \( t=0 \) is \( v=0 \), the velocity of particle at time \( t=2 \mathrm{~s} \) will be
(1) \( 1 \mathrm{~ms}^{-1} \)
(2) \( 4 \mathrm{~m} \mathrm{~s}^{-1} \)
(3) \( 2 \mathrm{~m} \mathrm{~s}^{-1} \)
(4) \( 2 \sqrt{2} \mathrm{~ms}^{-1} \)
