A mass of 2.0 kg is suspended from the ceiling of an elevator by a rope. What is the tension in the rope when the elevator (i) accelerates upward at $1.5 \textrm{ m/s}^2$? (ii) accelerates downward at $1.5 \textrm{ m/s}^2$?
  1. (i) 22.6 N; (ii) 16.6 N
  2. Because the mass is hanging from the elevator itself, the tension in the rope will not change in either case.
  3. (i) 22.6 N; (ii) 19.6 N
  4. (i) 16.6 N; (ii) 19.6 N
