Final answer:
The net force of the given forces (40N, 42N, 25N, 15N, 13N, 27N, 20N, and 18N) is the sum total, which is 200 N.
Step-by-step explanation:
The question is asking to calculate the net force given a list of individual forces. The net force is the vector sum of all the forces acting on an object. When forces are given in one dimension and have the same direction, you simply add the magnitudes to find the net force. In this case, we add 40N, 42N, 25N, 15N, 13N, 27N, 20N, and 18N together to find the total.
Calculating the sum, we have: 40N + 42N + 25N + 15N + 13N + 27N + 20N + 18N = 200N. So, the net force acting on the object would be 200 N.
