Question: A box of mass m 2 = 3.5 kg rests on a frictionless horizontal shelf and is attached by strings to boxes of masses m

A box of mass m₂ = 3.5 kg rests on a frictionless horizontal shelf and is attached by strings to boxes of masses m₁ = 1.5 kg and m₃ = 2.5 kg, which hang freely, as shown in Figure 4-39. Both pulleys are frictionless and massless. The system is initially held at rest. After it is released, find

(a) The acceleration of each of the boxes,

(b) The tension in eachstring.
