For This Problem, Assume No Friction

question 76

Multiple Choice

For this problem, assume no friction. A mass m₂ = 3.5 kg rests on a horizontal table and is attached by strings to masses m₁ = 1.5 kg and m₃ = 2.5 kg as shown. The masses m₁ and m₃ hang freely. The system is initially held at rest. After it is released, the acceleration of mass m₂ will be

• A) zero
• B) 1.3 m/s²
• C) 5.2 m/s²
• D) 8.7 m/s²
• E) 9.8 m/s²
