A car travels in a straight line along a straight and horizontal road. During a stretch of 10 kilometers, the car maintains a constant speed of 72 km/h. An observer, standing at a fixed point on the road, records the car's movement and notes the vehicle's positions every minute. After 15 minutes of observation, the positions recorded by the observer are: after 0 minutes, the car is at kilometer 0; after 5 minutes, the car is at kilometer 6; and after 10 minutes, the car is at kilometer 12. Based on this information and considering that the car maintains its constant speed, discuss: 1) What is the trajectory of the car's movement on this stretch of the road? 2) How can the concepts of kinematics and geometry be applied to determine the car's trajectory? If necessary, use formulas and physical principles to justify your answer.
