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 (19,17.2,0), radius= 0.5, color = color.red) vcart vector (5.6,0,0) t = 0 dt = 0.1 while t < 0.8: (a) At what location is the fan cart when the script starts? (0 7 = fancart.pos= fancart.pos + vancart*dt t = t + dt Submit Answer Tries 0/8 (b) What is the velocity of the fan cart when the script starts? -( V = Submit Answer Tries 0/8 (c) At what time does the script stop running? tf = Submit Answer Tries 0/8 m m/s
