Question

you push your friend again sitting on a swing with 200n of force. she accelerates at a rate of 5 m/s². what is the friends mass?

Explanation:

Step1: Recall Newton's second - law formula

$F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration.

Step2: Rearrange the formula to solve for mass

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

Step3: Substitute given values

Given $F = 200N$ and $a=5m/s^{2}$, then $m=\frac{200}{5}$.

Answer:

$40kg$
