SUMMARY
The problem involves calculating the force exerted by the elevator floor on a person weighing 0.6 kN while the elevator accelerates downward at 3 m/s². Using Newton's second law, F = ma, the effective force can be determined by considering both the gravitational force and the elevator's acceleration. The net force acting on the person is the difference between the gravitational force (0.6 kN) and the force due to the elevator's acceleration, resulting in a calculated force of 0.3 kN acting on the person.
