The motion of a particle is described by the equation \( \mathrm{x}=\mathrm{a}+\mathrm{bt}^{2} \) where \( \mathrm{a}=15 \mathrm{~cm} \) and \( \mathrm{b}=3 \mathrm{~cm} / \mathrm{sec}^{2} \). Its instantaneous velocity at time \( 3 \mathrm{sec} \) will be :-
(1) \( 36 \mathrm{~cm} / \mathrm{sec} \)
(2) \( 18 \mathrm{~cm} / \mathrm{sec} \)
(3) \( 16 \mathrm{~cm} / \mathrm{sec} \)
(4) \( 32 \mathrm{~cm} / \mathrm{sec} \)
