Question

A 15.0Kg monkey hangs from a cord suspended from the ceiling of an elevator. the cord can withstand a tension of 200N and breaks as the elevator accelerates. what was the elevator's minimum acceleration ( in magnitude the direction)? taken g=10.0meter per second square

Answer 1

Tension - mg = ma
Tension = m (g+a) = 15.0 (10.0 + a)
so
150 + 15 a = 200
15 a = 50
a = 50/15 = 3.33 m/s^2
