The fan cart in the video below is observed to [[183_notes:acceleration|accelerate]] uniformly to the right. The air exerts a [[183_notes:constantf|constant force]] on the blades that is around 0.45N. Determine the how far the has traveled after 2.2s if the cart starts from rest. | The fan cart in the video below is observed to [[183_notes:acceleration|accelerate]] uniformly to the right.
