1. An object (mass 0.20 kg) hangs at rest from a spring (mass 0.10 kg). The object is then pulled down 0.30 m and released at time so that it vibrates up and down through its original position. It takes 0.45 s to move from the lowest point in its motion to its highest. a. Draw a position vs. time graph for the object. Take the coordinate system origin to be the position the object was initially hanging at with the positive direction upwards, and let ???? = 0 ???? be when the object is released. Include an equation corresponding to the graph. Plug in all relevant values. b. Sketch a velocity vs. time graph directly beneath the position vs. time graph it with the same horizontal scale so the two graphs can be easily compared. Write down an equation corresponding to this graph, but do not plug in any values. c. Determine the spring constant of the spring
