the forces acting on a child sitting in a seat are described by the free - body diagram shown. what is the net force acting on the child? $f_n = 100 n$ $f_g=-100 n$ -100 n 0 n 100 n 200 n

Answer

Explanation:

Step1: Recall net - force formula

The net force $F_{net}$ is the sum of all forces acting on an object. If we have two forces $F_N$ (normal force) and $F_g$ (gravitational force), then $F_{net}=F_N + F_g$.

Step2: Substitute given values

We are given that $F_N = 100\ N$ and $F_g=- 100\ N$. Substituting these values into the formula, we get $F_{net}=100+( - 100)$.

Step3: Calculate the result

$100+( - 100)=100 - 100=0\ N$.

Answer:

B. 0 N
