Question

susan is sitting on a roller coaster cart as it reaches the bottom of a big loop. earths gravity is pulling down on susan with a force of 600 n. the seat of the cart is pushing up on susan with a force of 1,200 n. assume all other forces on susan are balanced. which statement describes the forces on susan? the forces are balanced, so there is no net force on susan. the forces are unbalanced, so there is a net force on susan.

Explanation:

Step1: Determine the direction of forces

Gravity acts downward (\(F_{g}=600\ N\)), seat force acts upward (\(F_{s}=1200\ N\)).

Step2: Calculate the net force

Net force \(F_{net}=F_{s}-F_{g}\). Substitute values: \(F_{net}=1200 - 600=600\ N\) (upward). Since \(F_{net}
eq0\), forces are unbalanced.

Answer:

The forces are unbalanced, so there is a net force on Susan.
