In this animation the pendulum is the same as Animation 1 (the net force on the bob is shown as a green arrow), the spring has a spring constant of \(1.30666\text{ N/m}\), and the mass of the red ball...In this animation the pendulum is the same as Animation 1 (the net force on the bob is shown as a green arrow), the spring has a spring constant of \(1.30666\text{ N/m}\), and the mass of the red ball attached to the spring is \(2\text{ kg}\) (the net force on the red ball is represented by the blue arrow).
