A ball of mass m moves along a thread that rotates around one end at an angular velocity ω. The thread is at an angle α with respect to the axis of rotation. Using Lagrange's equations, find the equations of motion of mass along the thread and the time it takes for the ball to slide with nor if it starts from a state of rest at the top.
