Velocity of a particle varies as
\( \mathrm{P} \) \( v=2 t^{3}-3 t^{2} \) in \( \mathrm{km} / \mathrm{hr} \)
W.
If \( t=0 \) is taken at \( 12: 00 \) noon
What is the velocity of the particle at \( 12: 00 \) noon?
(A) \( 0.5 \mathrm{~km} / \mathrm{hr} \)
(B) Zero
(C) \( 1 \mathrm{~km} / \mathrm{hr} \)
(D) \( 2 \mathrm{~km} / \mathrm{hr} \)
