A block is attached to a spring. It is sliding back and forth on a frictionless surface. The graph below represents the displacement of the block from equilibrium as a function of time. A 20 ~ The amplitude of the motion is 30cm. The speed at point C is at a maximum. Remember that this is a plot of displacement versus time. It often helps to imagine the block moving back and forth as in an animation. What part of the animation corresponds to what points on the graph? Submit Answer Incorrect. Tries 5/10 Previous Tries
