Question

Two blocks, each of mass m 5
3.50 kg, are hung from the ceiling
of an elevator as in Figure P5.31.
(a) If the elevator moves with an
upward acceler ation aS
of magnitude
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 a string breaks?
