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?
To find the net force on the object, we need to find the sum of the two forces.
Since the first force is directed west, its magnitude is negative. So we have -30 N.
Since the second force is directed east, its magnitude is positive. So we have +12 N.
Therefore, the net force on the object is -30 N + 12 N = -18 N.
