Please formulate the given problem.
Problem- A 75 kg passenger is seated in a cage in the Sling Shot, a carnival ride. Giant bungee cords are starched as the cage is pulled down, and then they rebound to launch the cage straight up. After the rapid launch, the cord goes slack and the cage moves under the influence of gravity alone.
Part 1- What is the rider's apparent weight after the cords have gone slack and the cage is moving upward?
Provide me the right evaluation of above problem.
