Problem

Inside a moving elevator, the scale under a 60 kg60\,\text{kg} passenger shows 500 N500\,\text{N}. Take g=9.8 m s−2g = 9.8\,\text{m}\,\text{s}^{-2}. What is the elevator’s acceleration? (a) 1.7 m s−21.7\,\text{m}\,\text{s}^{-2} downward (b) 1.5 m s−21.5\,\text{m}\,\text{s}^{-2} upward (c) 1.5 m s−21.5\,\text{m}\,\text{s}^{-2} downward (d) 3.0 m s−23.0\,\text{m}\,\text{s}^{-2} downward
