Two blocks each of mass m = 2.98 kg are fastened to the top of an elevator as in the figure.
(a) If the elevator has an upward acceleration a = 1.60 m/s2, find the tensions T1 and T2 in the upper and lower strings.
T1=
T2=
(b) If the strings can withstand a maximum tension of 88.0 N, what maximum acceleration can the elevator have before the upper string breaks?
