An object of inertia 0.5kg is hung from a spring, and causes it to extend 5cm. in an elevator accelerating downward at 2 m/s^2 , how far will the spring extend if the same object is suspended from it? draw the free body diagrams for both the accelerating and non-accelerating situations.

Identify the amplitude on the diagram and give the correct description. question 3 options: a because amplitude is the distance from wave crest to wave crest. b because the wavelength shows amplitude. c because amplitude is the distance between a crest (or trough) and rest. d because wavelength show amplitude.
