. The velocity of this particle is continuously changing.
with respect to time 
to find an expression for velocity. ![\begin{aligned}v(t) &= \frac{d}{dt}[x(t)] \\ &= \frac{d}{dt} \left[ 7.4 + 9.2\, t - 2.1\, t^{3}\right]\\ &= 9.2 - 6.3\, t^{2}\end{aligned}](/tpl/images/1407/2743/4e606.png)
.
, velocity would be 
.
changes with time
