what is the net force?
what is the acceleration?

Explanation:

Step1: Calculate net - force

Since the two forces are in the same direction, we add them. The net - force $F_{net}$ is the sum of the two forces. $F_{1}=40N$ and $F_{2}=100N$. So, $F_{net}=F_{1}+F_{2}$.
$F_{net}=40 + 100=140N$

Step2: Calculate acceleration

We use Newton's second - law $F = ma$, where $F = F_{net}$, $m = 20kg$, and we want to find $a$. Rearranging the formula for $a$, we get $a=\frac{F_{net}}{m}$.
$a=\frac{140}{20}=7m/s^{2}$

Answer:

Net Force: 140 N
Acceleration: 7 m/s²
