The displacement of a particle starting from rest (at $t = 0$) is given by $s = 6{t^2} - {t^3}$. The time in seconds at which the particle will attain zero velocity again, is ..... $\sec$

The displacement of a particle starting from rest (at $t = 0$) is given by $s = 6{t^2} - {t^3}$. The time in seconds at which the particle will attain zero velocity again, is ..... $\sec$
$v = \frac{{ds}}{{dt}} = 12t - 3{t^2}$
Velocity is zero for $t = 0$ and $t = 4\sec $
