A particle, moving in a straight line, passes through a fixed point O
with a velocity of $8 m s^{-1}$
Its acceleration, $a\ m^{-2}$, t seconds after passing O is given by $a=12-6t$. Find
(i) the velocity of the particle when $t=2$,
(ii) the displacement of the partial from O when $t=2$.
I know that if $a=12-6t$.
Then $v=12t+3t^2+C$
