Question
Which of the following units is equivalent to kg·m/s?
Correct Answer
Option C is the correct answer.
Detailed Explanation
kg·m/s is the unit of momentum (p = mv). Ns (newton-second) is impulse, which equals change in momentum, so it has the same dimensions: [F][T] = MLT⁻² * T = MLT⁻¹.
Hint
Recall that impulse = force × time, and has the same unit as momentum.
