8) Two blocks with masses ma = 0.200 kg and m = 0.300 kg hang one under the other, as shown in the figure below. Find the tensions in the (massless) ropes in the following situations: (a) The blocks are at rest; (b) they move upward at 5 m/s; (c) they accelerate upward at 2.00 m/s'; (d) they accelerate downward at 2.00 m/s'. (e) If the maximum allowable tension is 10.0 N, what is the maximum possible upward acceleration?
