Assume all other forces on Candice are balanced. Which statement describes the forces on Candice?

 - The forces are balanced, so there is no net force on Candice.
 - The forces are unbalanced, so there is a net force on Candice.
To determine if there is a net force on Candice, look at the forces:
Earth's gravity is pulling Candice down with a force of 600 N.
The seat of the cart is pushing Candice up with a force of 1,200 N.
The forces are in opposite directions, and the forces have different magnitudes: 600 N and 1,200 N. This means that the forces are unbalanced, so there is a net force on Candice.
