The figure shows the acceleration$-$versus$-$time graph of a particle moving along the x$-$axis. The initial velocity of the particle is $20\mathrm{.}7$ m$/$s at

t$=0$ s$.$ What is the particle$$s velocity $($in m$/$s$)$ at

t$=3$ s$?$

The figure shows the acceleration$-$versus$-$time graph of a particle moving along the $x-$axis. The initial velocity of the particle is $20\mathrm{.}7\frac{m}{s}$ at $t=0s.$ What is the particle's velocity $($in $\frac{m}{s})$ at $t=3s?$
