5. A mass on a vertical spring is observed to have the displacement vs. time graph below. From the graph, what is the period of the motion in seconds? Explain or show how you got your answer. 6. If positive displacement is upward, indicate on the graph below at least one point where: A The velocity is maximum and upward. B = The velocity is maximum and downward C=The velocity is zero. D= The acceleration is maximum and negative. E = The acceleration is maximum and positive. F = The acceleration is zero. DISIECCO Identify the point with a small circle at the location and the assigned letter beside the circle. If it helpful, draw the velocity and acceleration graphs. t a n e 1.00 0.75 0.50 0.25 0.00 m 0 4 8 12 Time (seconds) 2 MacBook Air Page T= 16 20
