According to Newton’s First Law of Motion, an object in motion will stay in at the same speed and direction unless acted upon by an unbalanced force.
what is the answer
The correct answer is "an unbalanced force".
A runner exerting a running force of 325 N to the right is met with an air resistance force of 45 N to the left. What is the net force of the runner?(1 point)

280 N
To calculate the net force, we need to find the difference between the two forces exerted on the runner. Since both forces act in opposite directions (one to the right and one to the left), we subtract the smaller force from the larger force.
325 N (running force to the right) - 45 N (air resistance force to the left) = 280 N
Therefore, the net force acting on the runner is 280 N.
