A 12.5kg monkey hangs from a cord suspended from the ceiling of an elevator. The cord can withstand a tension of 157N and breaks as the elevator accelerates.
What was the magnitude of the elevator's minimum acceleration?
What was the direction of the elevator's minimum acceleration?

Tension=m(a+g) where a is in the upwarddirection.
