Question
The sketch below shows the position of a toy car that moves along a track while a fan is blowing and creating a
"headwind". The numbers indicate the time when the car was at a given position (some images overlap). The
"tic" marks are 10 centimeters apart. The positive x direction is to the right.

In the space below, make a motion diagram of the motion of the cart. Include arrows to represent the (1)
velocities and the (2) accelerations. Motion diagrams include: (1) dots to indicate positions (the dots are already
drawn), (2) labeled arrows between dots to represent velocities, and (3) labeled arrows above/below the dots
to represent accelerations. Put the acceleration arrows slightly above the dots when the cart is moving to the
right and slightly below the dots when the cart is moving to the left.
