FIGURE CP7.58 shows three hanging masses connected by massless strings over two massless, frictionless pulleys.
(a) Find the acceleration constraint for this system. It is a single equation relating a_1y, a_2y, and a_3y.
(b) Find an expression for the tension in string A.
(c) Suppose: m₁= 2.5 kg, m₂= 1.5 kg, and m₃= 4.0 kg. Find the acceleration of each.
(d) The 4.0 kg mass would appear to be in equilibrium. Explain why it accelerates.
