Velocity Plot

The velocity begins at a small constant value, as expected, for the climb up the lift hill. From that point on, the velocity increases as the track elevation drops, and the velocity drops as the elevation climbs. The brake run can be clearly seen, and is where the velocity steadily drops at the end of the track. The velocity should always remain positive. If Track Master encounters a negative velocity, calculations are halted and an error message is printed. The geometry of the track must then be modified to allow the car to finish the circuit.
