Question

what is the mass of a cannonball if a force of 2,500 n gives the cannonball an acceleration of 200 m/s²?
12.5 kg
15.0 kg
20 kg
25 kg

Explanation:

Step1: Recall Newton's second law

$F = ma$ (where $F$ is force, $m$ is mass, $a$ is acceleration)

Step2: Solve for mass $m$

$m=\frac{F}{a}$

Step3: Substitute values

Given $F = 2500\ N$ and $a=200\ m/s^{2}$, then $m=\frac{2500}{200}=12.5\ kg$

Answer:

12.5 kg
