The fan cart in the video below is observed to accelerate uniformly to the right. The air exerts a constant force on the blades that is around 0.45N. Determine the how far the fan cart has traveled after 2.2s if the cart starts from rest.
The displacement of the cart is given by,
Δxcart=xcart,f−xcart,i=vcart,xiΔt+12Fnet,xmcartΔt2
We can compute this displacement,
Δxcart=(0ms)(2.2s)+120.45N0.3kg(2.2s)2=3.6m
