The acceleration \['a'\] in \[m/{{s}^{2}}\] of a particle is given by \[a=3{{t}^{2}}+2t+2\] where \[t\] is the time. If the particle starts out with a velocity \[u=2\,m/s\] at \[t=0\], then the velocity at the end of 2 second is [MNR 1994; SCRA 1994]

• A.             12 m/s
• B.             18 m/s
• C.             27 m/s
• D.                         36 m/s
