At $t=0,$StarA is at the position $($:$0,7\mathrm{.}5{10}^{10},0$:$)m.$ At $t=8\mathrm{.}0{10}^{7}s,$StarA is at the position $($:$8\mathrm{.}632{10}^{11},-4\mathrm{.}039{10}^{10},0$:$)m.$ What is the magnitude of the average velocity of Star A in $\frac{m}{s}?$

Use VPython for your calculation. Be sure to define variables for the initial and final
