Consider the following VPython script that was written to model the motion of a fan cart.

You may assume the script uses SI units.

from visual import $*$

fancart $=$ sphere$($pos $=$ vector$(15\mathrm{.}8,11\mathrm{.}6,0),$ radius $=0\mathrm{.}5,$ color $=$ color.red$)$

vfancart $=$ vector$(8\mathrm{.}66,0,0)$

t $=0$

dt $=0\mathrm{.}1$

while t $<0\mathrm{.}5$:

fancart.pos $=$ fancart.pos $+$ vfancart$*$dt

t $=$ t $+$ dt

$($a$)$ At what location is the fan cart when the script stops running?

r$$ f$=$
