Question

Problem 5: A cord with length L 2 m has a ball of mass m 1 kg attached to the end. The ball is released from rest, when the cord makes an angle of 30° with the vertical. 1) How much work does the gravitational force do on the ball from A to B? 2) What is the speed of the ball at point B? 3) What is the tension in the cord at point B? 4) What initial velocity vo should be given to the pendulum at A, in order to swing down and then up to point C?

    The ball has a mass \(m\) and is attached to the cord of length \(I\). The cord is tied at the top to a swivel and the ball is given a velocity \(\mathbf{v}_{0}\). Show that the angle \(\theta\) which the cord makes with the vertical as the ball travels around the circular path must satisfy the equation tan \(\theta \sin \theta=v_{0}^{2} / g l\). Neglect air resistance and the size of the ball.
