Question

f_{net}=net force=forces added
what was the net force acting on the box?
120 newtons to the right.
160 newtons to the right
120 newtons to the left
160 newtons to the left
f_{net}=100n + 60n = 160n right

Explanation:

Step1: Determine the direction of forces

Both forces are acting to the right.

Step2: Calculate the net force

$$F_{NET}=100N + 60N$$
$$F_{NET}=160N$$

Answer:

160 Newtons to the right.
