Identical objects, Object X and Object Y, are tied together by a string and placed at rest on an incline, as shown in the figure. The distance between the center of mass of each object is 2 m. The system of the two objects is released from rest, and a graph of the system's center of mass velocity as a
function of time is shown. Based on the data, approximately how much time will it take the center of mass of Object X to reach point J near the bottom
of the incline?
