You are doing some spring cleaning and decide to clean out your house. you want to make a new window in your wall with which to see nature come to life, so you tie a heavy mass to a short string and attach the string to a beam in your ceiling so it can swing freely like a pendulum. you lift the ball and let it go for practice, and it takes exactly 0.5 s to come right back to you. ready for the real thing, you quadruple the length of the pendulum. were it to swing freely also, it would take s to return to you after you let it go.
