Answer

Explanation:

Step1: Recall Newton's second - law formula

Newton's second law is $F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. We can rewrite it as $a=\frac{F}{m}$.

Step2: Analyze the case of equal forces

When $F_1 = F_2$, from $a=\frac{F}{m}$, the object with smaller mass will have higher acceleration. The mass of the paper - plane is $4.5\ g=0.0045\ kg$ and the mass of the airplane is $80000\ kg$. So the paper - plane has higher acceleration and should be colored green, and the airplane has lower acceleration and should be colored purple.

Step3: Analyze the case of doubling the force

From $a=\frac{F}{m}$, if $m$ is constant and $F$ is doubled (new $F' = 2F$), then new $a'=\frac{F'}{m}=\frac{2F}{m}=2a$. So the acceleration doubles.

Answer:

  1. Color the paper - plane green and the airplane purple.
  2. The acceleration doubles.
