$${\mathrm{v}}_{\mathrm{avg}}=\frac{\mid △\mathbf{r}\mid }{△\mathrm{t}}=\frac{2\mathrm{rsin}\left(\theta /2\right)}{\mathrm{r}\theta /\mathrm{v}}$$$$=\mathrm{v}\left[\frac{\sin \left(\theta /2\right)}{\left(\theta /2\right)}\right],$$$${\mathrm{a}}_{\mathrm{avg}}=\frac{\mid △\mathbf{v}\mid }{△\mathrm{t}}=\frac{2\mathrm{vsin}\left(\theta /2\right)}{\mathrm{r}\theta /\mathrm{v}}$$$$=\frac{{\mathrm{v}}^2}{\mathrm{r}}\left[\frac{\sin \left(\theta /2\right)}{\left(\theta /2\right)}\right].$$
