$\dfrac{16}{9}\ s$

Step-by-step explanation:

Given

$s(t)=-t^3+2t^2+\frac{3}{2}$

Average velocity is given by

$v_{avg}=\dfrac{\int vdt}{\int dt}$

$v_{avg}=\dfrac{-\frac{t^4}{4}+\frac{2}{3}t^3+1.5t}{t}\\\\v_{avg}=-\frac{t^3}{4}+\frac{2}{3}t^2+1.5$

Now, equate the average and instantaneous velocity

$-\frac{t^3}{4}+\frac{2}{3}t^2+1.5=-t^3+2t^2+1.5\\\\\Rightarrow -\dfrac{3t^3}{4}+\dfrac{4t^2}{3}=0\\\\\Rightarrow t^2\left(-\dfrac{3}{4}t+\dfrac{4}{3}\right)=0\\\\\Rightarrow t=\dfrac{16}{9}\ s$
