Multiple-Object Systems with Friction: in the Figure, Two Wooden Blocks

question 76

Multiple Choice

Multiple-object systems with friction: In the figure, two wooden blocks each of 0.30 kg mass are connected by a string that passes over a very light frictionless pulley. One block slides on a horizontal table, while the other hangs suspended by the string, as shown in the figure. At time t = 0, the suspended block is 0.80 m over the floor, and the blocks are released from rest. After 2.5 s, the suspended block reaches the floor. What is the coefficient of kinetic friction between the table and the sliding block?

• A) 0.35
• B) 0.52
• C) 0.84
• D) 0.65
• E) 0.95
