Multiple Springs (Parallel and Series)

You are given a spring with spring constant $k.$ Now, you cut the spring in half—each half now has spring constant $k'.$ Find $k'$ in terms of $k.$ (Answer this question in the text box below)

Follow-up question (for you to think about): Does your answer make intuitive sense? Do you expect the spring to get "stiffer" or "looser" if you cut it?
