Solution Steps

Step 1: Identify the forces

The forces acting on the person in the elevator are:

  • W: The weight of the person acting downwards (600 N).
  • N: The normal force from the elevator floor acting upwards.
Step 2: Set up the net force equation

Since the elevator is moving downwards and its speed is increasing, the net force is downwards. The equation of motion is

|F_net| = W - N
Step 3: Solve for N

We are given that |F_net| = 50 N and W = 600 N. Plugging these values into the net force equation gives

50 N = 600 N - N

Solving for N, we get

N = 550 N

Final Answer: The normal force is 550 N.
