Final answer:
This scenario requires the application of kinematic equations and dynamics principles from physics to analyze the motion of a car travelling over a hill shaped like a parabola.
Step-by-step explanation:
The scenario where a 0.8-mg car travels over a hill in the shape of a parabola, with an initial speed of 9 m/s and acceleration of 3 m/s², involves the application of the principles of kinematics and dynamics in physics. The situation can be analyzed using the equations of motion, considering the forces involved as the car travels up and down the parabolic path.
