Use the graph to answer the question which of these objects is moving at a rate of 2 ft./s is it object a object BC or all of the objects?

Answer 1

The graph was not provided, so I cannot analyze it to answer the question accurately. However, if the graph shows the position-time relationship for each object, you would need to look for the object whose position is changing at a constant rate of 2 ft/s. If there is an object whose position is changing at this constant rate throughout the entire time interval represented on the graph, then that would be the object moving at a rate of 2 ft/s.
