# Friction: Pushing a file cabinet

You are pushing a filing cabinet across a rough floor (mk = 0.33) in a straight line at a constant speed. Which of the following statements about the magnitudes of the forces acting on the filing cabinet are correct?

1. true false if you exerted twice the force, the cabinet would accelerate across the floor.
2. true false the force that you exert on the filing cabinet will be less than its weight.
3. true false the force that you exert on the filing cabinet will be more than the frictional force on the cabinet.
4. true false the force that you exert on the filing cabinet will be equal to the frictional force on the cabinet.
5. true false the force that you exert on the filing cabinet will be more than its weight.

#### Solution Preview

1. If you exerted twice the force, the cabinet would accelerate across the floor.

When the cabinet is moving with constant velocity it is in kinetic equilibrium and the resultant of all force i.e. net force is zero. The friction force is equal to applied force. If the force applied is doubled, friction is still the same and now the net ...
