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 $0.45 N$. Determine the how far the has traveled after $2.2 s$ if the cart starts from rest.

• The fan cart accelerates uniformly to the right.
• The force by the air on the blades if $0.45 N$.
• The fan cart travels to the right for $2.2 s$.
• The fan cart starts from rest.
• The fan cart experiences several forces including:
  • the force of the air on the blades (to the right)
  • the gravitational force due to the interaction with the Earth (directly downward)
  • the force applied by the track (directly upward)
  • a frictional forces and air resistance that resist the motion
• The acceleration due to gravity is 9.8 $\dfrac{m}{s^2} and is directed downward.

• The mass of the fan cart is not given, but can be found online ($m_{cart} = 0.3 kg$).

• Over the interval that we care about it, we will assume the net force is doesn't change. That is, the cart experiences constant force motion.
• As a result, the motion occurs only in the horizontal direction.

 
 * The forces acting on the fan cart (the system's interactions with its surroundings) are represented in this free-body diagram.

• The net force acting on the fan cart is the sum of all the forces, $\vec{F}_{net} = \sum \vec{F}_i = \langle 0.45, 0, 0 \rangle N$.
