SUMMARY
The total force acting on a car with a mass of 850 kg moving at a constant speed of 1.44 m/s is zero, as established by Newton's first law of motion. Since the car is not accelerating, the net force (F_net) is zero, confirming that no external force is acting on it in either direction. The equation F=ma is applicable, but velocity should not be substituted for acceleration in this context. Thus, the total force remains unchanged regardless of the direction of motion.
