Question

ivan pushes a dresser with full drawers across his carpeted floor. what could ivan do to reduce the amount of friction between the dresser and the floor? select two options.

• place some smooth tiles under the dresser
• remove or turn off sources of wind
• move the dresser at a slower speed
• remove the drawers from the dresser

Explanation:

1. Placing smooth tiles under the dresser replaces the high-friction carpet surface with a smoother one, directly reducing sliding friction between the surfaces.
2. Removing the drawers decreases the total weight of the dresser. Since friction force is proportional to the normal force (which equals the object's weight on a level surface), reducing weight lowers the friction force.
3. Wind sources affect air resistance, not surface friction, and sliding friction is independent of constant speed, so those options do not reduce friction between the dresser and floor.

Answer:

A. place some smooth tiles under the dresser
D. remove the drawers from the dresser
