Question

1. how much force would it take to push another, larger friend who has a mass of 70 kg to accelerate at the same rate of 4 m/s²?

Explanation:

Step1: Recall Newton's second - law formula

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

Step2: Identify given values

$m = 70\ kg$, $a=4\ m/s^{2}$

Step3: Calculate the force

$F=70\times4 = 280\ N$

Answer:

$280\ N$
