III A \(75 \mathrm{~kg}\) passenger is seated in a cage in the Sling Shot, a carnival ride. Giant bungee cords are stretched as the cage is pulled down, and then they rebound to launch the cage straight up. After the rapid launch, the cords go slack and the cage moves under the influence of gravity alone. What is the rider's apparent weight after the cords have gone slack and the cage is moving upward?
