The velocity of a particle ( $v$ ) at an instant $t$ is given by $v=a t+b t^{2}$. The dimension of $b$ is (a) [L] (b) $\left[\mathrm{LT}^{-1}\right]$ (c) $\left[\mathrm{LT}^{-2}\right]$ (d) $\left[\mathrm{LT}^{-3}\right]$
(II) The speed, $v,$ of an object is given by the equation $v=A t^{3}-B t,$ where $t$ refers to time. What are the dimensions of $A$ and $B ?$
