## Physics for Scientists and Engineers: A Strategic Approach with Modern Physics (4th Edition)

$m = 0.25~kg$
On the graph, we can see that the acceleration is $a = 4~m/s^2$ when the force is $F = 1.0~N$. We can use this information to find the mass: $F = ma$ $m = \frac{F}{a}$ $m = \frac{1.0~N}{4~m/s^2}$ $m = 0.25~kg$
