Final answer:
A net force of 3200 newtons is required to accelerate a 1600 kg automobile forward at 2.0 m/s², as calculated using Newton's second law of motion.
Step-by-step explanation:
The net force needed to accelerate a 1600 kg automobile forward at 2.0 m/s² can be calculated using Newton's second law of motion, which states that Force equals mass times acceleration (F = m × a). To find the net force, we simply multiply the mass of the automobile by the acceleration.
F = m × a
F = 1600 kg × 2.0 m/s²
F = 3200 N
Therefore, a net force of 3200 newtons is needed to accelerate the 1600 kg automobile at 2.0 m/s².
