Analyze and Interpret Data 1. SEP Use Models Draw a freebody diagram of the stopper following a circular orbit around the tube handle, and washers hanging from the string. Indicate in your diagram the orbital speed (v) of the stopper, the centripetal force acting on the stopper (F.), and the force of gravily acting on the harrying washers (F,). 2. SEP Use Mathematics In Part I, calculate the orbital period (7, in seconds) of the stopper for the two orbital radii studied. Fill in Table 1 and show a sample of your calculations. Note: Remember that the period, 7, is the time per single revolution of orbit
