A runner exerting, a running force of 325 and to the right is met with an air resistance force of 45 and to the left what is the net force of the runner?
45n
370n
325n
280n
The net force of the runner is the vector sum of the running force and the air resistance force. Since the air resistance force is in the opposite direction to the running force, we subtract its magnitude from the magnitude of the running force:
Net force = 325 N - 45 N = 280 N
Therefore, the net force of the runner is 280 N.
