Question

1. for every action force, there is an __________ and opposite action force. equal unequal unbalanced differential 7. calculate: if a 100 n force moves an object at 5 m/s^2, how much mass does it have? (hint, you have to rearrange the force formula) 2000 kg 20 kg 0.05 kg

Explanation:

Question 4

Newton's third - law of motion states that for every action force, there is an equal and opposite reaction force.

Step1: Recall the force formula

The force formula is $F = ma$, where $F$ is force, $m$ is mass, and $a$ is acceleration. We need to solve for $m$, so we rearrange the formula to $m=\frac{F}{a}$.

Step2: Substitute the given values

We are given that $F = 100\ N$ and $a = 5\ m/s^{2}$. Substituting these values into the formula $m=\frac{F}{a}$, we get $m=\frac{100}{5}$.

Step3: Calculate the mass

$\frac{100}{5}=20\ kg$.

Answer:

A. equal
