Essay

For the problems below, find: a) $\Delta \mathrm{s}$ and b) $\overline{\mathrm{v}}$ for each function expressing distance $\mathrm{s}$ in terms of time $\mathrm{t}$ . 21) $s=5 t+3$
-Given $s=4 t^{2}+16 t-5$ , find $\bar{v}$ at $t=3$ and $\Delta t=1$ , where $s$ is in metres and $t$ is in seconds.
