_{2}= 1.5 kg rests on a horizontal table. The coefficients of friction between m

_{2}and the table are µ

_{s}= 0.3 and µ

_{k}= 0.25. The mass m

_{2}is attached by strings to masses m

_{1}= 2.5 kg and m

_{3}= 4.5 kg as shown. Masses m

_{1}and m

_{3}hang freely. The system is initially held at rest. After it is released, the acceleration of m

_{2}is approximately A) 1.9 m/s

^{2 }B) 2.4 m/s

^{2 }C) 3.0 m/s

^{2 }D) zero E) 13 m/s
