The graph shown above represents the displacement vs. time graph of a 70-g object undergoing a simple harmonic motion, in a spring system.
Determine: A) the stiffness of the spring B) the mechanical energy of the motion C)the magnitude of the maximum acceleration D)the time it takes to reach one turning point from the other turning point if the mass is changed to 280 grams.
