Question

What is the mass of a box that

requires a force of 27 N to be
accelerated to 4.0 m/s²?
O 6.8 kg
O2.3 kg
31 kg
O108 kg

Answer 1

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.”
