A force applied to an object of mass $\text{m1}$ produces an acceleration of 3.00 ms$^{-2}$. The same force applied to a second object of mass $\text{m2}$ produces an acceleration of 1.00 ms$^{-2}$. What is the value of the ratio $\large\frac{\text{m1}}{\text{m2}}$?

Can you answer this question?

Toolbox:
  • According to Newton's second law: When viewed from an inertial reference frame, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
Answer:
According to Newton's second law, $F = ma$
$\Rightarrow F = m1a1 = m2a1$.
Given, $a1 = 3 m/s^2$ and $a2 = 1 m/s^2, \rightarrow F = m1 \times 3 = m2 \times 1 \rightarrow \large\frac{m1}{m2} $$= \large\frac{1}{3}$
