Change the mass of the orange-colored hooked-object from 100 g to 50 g (the control box for "Mass" is at the top left of the spring), then attach the object to the free end of the spring. The spring is stretched, and the object starts to move up and down in an oscillatory motion but slows down due to damping. When the motion stops, the spring-object system is in its equilibrium state. Carefully read the position of the lowest ring of the spring and record it in the table below as y 0 . This is how much the spring is stretched due to the weight of the object. Repeat the process for an additional five values of M. Keep three significant figures for the calculated values of Mg (in N ). The estimated digit of y o should be the mm(0.001 m) digit.
