Two forces act on an object. One force has a magnitude of 30N directed west, and the other force has a magnitude of 12 N directed east. What is the net force on the object?(1 point) Responses 42 N east 42 N east 18N east 18N east 18N west 18N west 42N west

Answer 1

To find the net force on the object, we need to take into account the directions of the forces acting on it.

1. The first force is 30 N directed west.
2. The second force is 12 N directed east.

Since west can be considered as a negative direction and east as a positive direction, we can represent the forces as:

• Force 1 (west): -30 N
• Force 2 (east): +12 N

Now, we add the two forces together to get the net force:

\[ Net\ force = -30\ N + 12\ N = -18\ N \]

The negative sign indicates that the net force is directed west. Thus, the net force is 18 N directed west.

The correct response is 18 N west.
