Answer:
x=2t3−4t2+3t−4
\implies \: \frac{dx}{dt} = v \: = 6 {t}^{2} - 8t + 3⟹dtdx=v=6t2−8t+3
\implies \: \frac{ {d}^{2}x }{d {t}^{2}} = 12t - 8⟹dt2d2x=12t−8
So
Initial velocity
6 \times {0}^{2} - 8 \times 0 + 3 = 3 \: \: unit6×02−8×0+3=3unit
Initial acceleration
= 12 \times 0 - 8 = - 8 \: unit=12×0−8=−8unit
