The frictioniess collar at A has a mass of 25g and the rope ABC passes over a frictionless pulley at B. Knowing the spring is initially unstretched and has a constant of 7500Nm, ignoring the size of the pulley, determine the distance d that the collar travels down when released. Hint: The spring displaces by the change in distance between A and B, AB - AB If you end up with an equation that is difficult to solve, think about using a trial and error solution like that in video 1-03. As always, include a FBD and clearly label all variables used in your calculations. 1950m Answer(s): 1750mm C Initial A Final B.
