The function $s=f(t)$ gives the position of a body moving on a coordinate line, with $s$ in meters and $t$ in seconds. Find the body's displacement and average velocity for the given time interval.

$s=4t^2+3t+9,0t2$

A$.22m,11\frac{m}{sec}$

B$.14m,19\frac{m}{sec}$

C$.22m,22\frac{m}{sec}$

D$.40m,20\frac{m}{sec}$
