Two blocks each of mass 3.50 kg are fastened to the top of an elevator as in Figure P4.21. (a) If the elevator accelerates upward at 1.60 m/s2, find the tensions T1 and T2 in the upper and lower strings. (b) If the strings can withstand a maximum tension of 85.0 N, what maximum acceleration can the elevator have before the first string breaks?FIGURE P4.21
