Two blocks, each of mass m = 2.85 kg are hung from the ceiling of an elevator as in the figure below. (a) If the elevator moves with an upward acceleration a→ of magnitude 1.1 m/s2, find the tensions T1 and T2 in the upper and lower strings. T1 = N T2 = N (b) If the strings can withstand a maximum tension of 69.4 N, what maximum acceleration can the elevator have before a string breaks? m/s2
