A car with a mass of 1,200 kg accelerates from rest to 20 m/s in 5 seconds. Assuming constant acceleration, what is the net force acting on the car during this time?
✓ Correct Answer: Option B
First, calculate acceleration (a = Δv/Δt = 20 m/s / 5 s = 4 m/s²). Then, use Newton's Second Law (F = ma). F = 1200 kg * 4 m/s² = 4800 N.
