A toy car moves along a straight east-west track. The position of the car is measured relative to a red
dot on the track. We consider the positive-x-direction to point east. In this one-dimensional problem, x,
Vx, and a, represent the x-components of the car's position, velocity, and acceleration vectors,
respectively. Below is a graph of x-versus-t.
