The acceleration ' \( a \) ' in \( \mathrm{m} / \mathrm{s}^{2} \) of a particle is given by
P \( a=3 t^{2}+2 t+2 \) where \( t \) is the time. If the particle starts

W out with a velocity \( u=2 \mathrm{~m} / \mathrm{s} \) at \( t=0 \), then the velocity at the end of 2 second is
(1) \( 12 \mathrm{~m} / \mathrm{s} \)
(2) \( 18 \mathrm{~m} / \mathrm{s} \)
(3) \( 27 \mathrm{~m} / \mathrm{s} \)
(4) \( 36 \mathrm{~m} / \mathrm{s} \)
