Question

consider this situation: a student attaches a rope to his book bag and drags the bag across the floor at a constant speed. of the forces listed, identify which act upon the bag. tap to select the forces that are present. normal gravity applied friction tension air resistance check answers

Explanation:

1. Gravity: Always acts on objects with mass, pulling the bag down.
2. Normal Force: The floor exerts an upward normal force to balance gravity (since the bag isn’t accelerating vertically).
3. Applied Force (Tension): The rope exerts a tension (applied) force to drag the bag horizontally.
4. Friction: Since the bag moves at constant speed, friction opposes the motion (balanced by tension).
5. Air Resistance: Negligible here (slow, short - distance movement on floor, so not a significant force acting on the bag in this context).

Answer:

Normal, Gravity, Applied (Tension), Friction
