5. A mass m₂ = 1.5 kg rests on a horizontal table. The static and kinetic coefficients of friction between m₂ and the table are μₛ = 0.3 and μₖ = 0.25, respectively. The mass m₂ is attached by strings to masses m₁ = 2.5 kg and m₃ = 4.5 kg as shown in the right. 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
