- 1 Material A Material B 2 Blocks 1 And 2 Are Connected By A Light String That Passes Over A Pulley With Negligible Mass 1 (398.15 KiB) Viewed 46 times
1 Material A Material B 2 Blocks 1 and 2 are connected by a light string that passes over a pulley with negligible mass and friction, as shown in the figure. Block 1 is on a table covered with two different materials, A and B. The two-block system is released from rest, and the speed of block 1 begins to increase. When block 1 reaches material B, its speed increases at a greater rate. Which of the following correctly compares the coefficient of kinetic friction betwo block 1 and the two materials and describes the change in the magnitude of the net force on block 2 as block 1 slides from material A to material B?
Coefficients Net Force μΑΣ μΒ Decreases Coefficients Net Force B μΑ > μΒ Increases Coefficients Net Force μΑ < μΒ Increases Coefficients Net Force D μΑ < μΒ Decreases
