1 newton means 1 kg-m/sec²
3 kg-m/sec² = 3 newtons
The expression 3 kg ⋅ m/s 2 represents a force of 3 newtons according to Newton's Second Law of Motion. The calculation shows that 1 kg·m/s² equals 1 newton, leading us to the conclusion that 3 kg ⋅ m/s 2 = 3 newtons . Thus, the correct answer is option b.
