The sphere has a mass of = 10 kg. It starts from rest when = 0. Neglect the mass of Rod AB and the size of the sphere. A) Graph the speed of the ball as a function of when the pendulum swings through a complete arc. The tension in the spring is 0 N when = 0. B) Plot six different curves on the same graph, representing one with no spring, and ones with different springs with spring constants of = 500 N/m, 1000 N/m, 1500 N/m, 2000 N/m, and one in which the ball just barely stops at the bottom of its stroke. C) What is the spring constant for this last case? Explain in words why your graphs look the way they do
