# Polly is pushing a box to the right across the floor with a force of 30 n. the force of gravity is 8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?

**Question: Polly is pushing a box to the right across the floor with a force of 30 n. the force of gravity is 8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?**

Polly is exerting a force of 30 N to push a box towards the right across the floor. Concurrently, the force of gravity acting on the box is 8 N, and the normal force is also 8 N. If Polly is unable to move the box, it would imply that the force of friction opposing her push must be equal to or greater than 30 N. This is because static friction must be overcome for motion to commence, and if the box remains stationary, the static frictional force is effectively balancing out Polly's applied force.
