A 17.0 kg monkey hangs from a cord suspended from the ceiling of an elevator.The cord can withstand a tension of 220 N and breaks as the elevator accelerates.

(A) What was the elevators maximum acceleration before the cord breaks?

(B) What is the tension in the string if the elevator accelerates with the same magnitude but opposite direction?

I got (A) as 3.14, I just don’t know how to approach (B).

Thanks in advance!
