Newton’s Second Law of Motion ties into this question. We can start by naming the formula of Newton’s Second Law:
Force = Mass • Acceleration
This formula can be rearranged to identify different measurements. For this case, the equation would look like:
Mass = Force / Acceleration
With this formula, we can plug in our given numbers:
Mass = 27 / 4
Mass = 6.75 kg
6.75 rounds up, meaning the mass of a box that requires a force of 27 N to be accelerated to 4.0 m/s^2 would be option A.) “6.8 kg.”
