Question

annie is walking her dog, lola. a squirrel just ran by, and lola is pulling forward on the leash with a force of 250 n. annie is pulling backward on the leash with a force of 180 n. assume all other forces on the leash are balanced. which statement describes the forces on the leash? the forces are balanced, so there is no net force on the leash. the forces are unbalanced, so there is a net force on the leash.

Explanation:

Step1: Determine the direction of forces

Annie pulls backward with \( F_{Annie}=250\ N \), Lola pulls forward with \( F_{Lola} = 180\ N \). Let the forward direction be positive.

Step2: Calculate the net force

The net force \( F_{net}\) on the leash is \( F_{net}=F_{Lola}-F_{Annie}\). Substitute the values: \( F_{net}=180 - 250=- 70\ N \). The negative sign indicates the direction is backward (opposite to the positive direction we assumed for forward). So the forces are unbalanced, and there is a net force on the leash.

Answer:

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