You are sitting in a cart at the top of a hill on a roller coaster. You have 10,500 J of GPE. If your current weight is 539 N, how tall is the hill you are sitting on?

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
