Final answer:
The net force (Fnet) on the person in the elevator can be calculated using Newton's second law. Substituting the given values, the net force is 689 N.
Step-by-step explanation:
The net force (Fnet) can be calculated using Newton's second law, which states that force (F) is equal to the product of mass (m) and acceleration (a). In this case, the person's mass is given as 80 kg. The apparent weight of the person in the elevator is 95 N, and this is equal to the net force acting on the person.
Since the elevator is accelerating downwards, the net force is the difference between the person's weight (mg) and the apparent weight. Therefore, we can calculate the net force using the equation:
Fnet = mg - Apparent weight
Substituting the given values, we have:
Fnet = (80 kg)(9.8 m/s^2) - 95 N = 784 N - 95 N = 689 N.
Therefore, the net force (Fnet) is 689 N.
