question 125

Multiple Choice

Multiple-object systems with friction: A rope pulls on the lower block in the figure with a tension force of 20 N. The coefficient of kinetic friction between the lower block and the surface is 0.16. The coefficient of kinetic friction between the lower block and the upper block is also 0.16. The pulley has no appreciable mass or friction. What is the acceleration of the 2.0 kg block?

• A) 4.1 m/s²
• B) 5.1 m/s²
• C) 8.4 m/s²
• D) 9.2 m/s²
