A 43.4 N object is in free fall, What is the magnitude of the net force when
the object encounters 24.4 N of air resistance?
Expert's answer
The net force equals to the vector sum of all forces acting on the object, the force of air resistance has the opposite direction to the weight,
thus F = W - Fair = 43.4 N - 24.4 N = 19 N
