Question
Sphere A is attached to the ceiling of an elevator by a string. A second sphere is attached to the first one by a second string. Both strings are of negligible mass. Here m1 = m2 = m = 3.33 kg.

(a) The elevator starts from rest and accelerates downward with 
a= 1.35 m/s2. What are the tensions in the two strings in newtons?
T1= ____ N
T2= ____ N

(b) If the elevator moves upward instead with the same acceleration what will be the tension in the two strings in newtons?
T1= _____ N
T2= _____ N

(c) The maximum tension the two strings can withstand is 95.0 N. What maximum upward acceleration (in m/s2) can the elevator have without having one of the strings break?
 _____ m/s2
