Exercício Unesp 2026/2 - Uma placa retangular P de espessura desprezível está em equilíbrio, ligada

A rectangular plate P of negligible thickness is in equilibrium, connected by two ideal strings, one blue (string 1) and the other red (string 2), to two identical blocks, A and B, each with a mass of 1 kg, as shown in Figure 1. The plate and the blocks are homogeneous, have their masses uniformly distributed, and the pulleys are ideal. Plate P is rotated and held at rest, in the situation shown in Figure 2. Assuming g = 10 m/s², knowing that sin (θ) = 0.6 and neglecting all friction, the initial vertical acceleration of plate P, when released from the situation shown in Figure 2, is: (A) 2.0 m/s². (B) 1.5 m/s². (C) 2.5 m/s². (D) 1.0 m/s². (E) 3.0 m/s².
