a net force of 17 n is applied to an object, giving it an acceleration of 2.5 m/s². what is the mass of the object?
kg

Explanation:

Step1: Recall Newton's second - law formula

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

Step2: Substitute given values

Given $F = 17\ N$ and $a=2.5\ m/s^{2}$. Then $m=\frac{17}{2.5}$.

Step3: Calculate the mass

$m = 6.8\ kg$.

Answer:

$6.8$
