A Mass M₂ = 1

question 66

Multiple Choice

A mass m₂ = 1.5 kg rests on a horizontal table. The coefficients of friction between m₂ and the table are µ_s = 0.3 and µ_k = 0.25. The mass m₂ is attached by strings to masses m₁ = 2.5 kg and m₃ = 4.5 kg as shown. Masses m₁ and m₃ hang freely. The system is initially held at rest. After it is released, the acceleration of m₂ is approximately

• A) 1.9 m/s²
• B) 2.4 m/s²
• C) 3.0 m/s²
• D) zero
• E) 13 m/s²
