Question

Problem 2. The ball with mass m is attached to two elastic cords each of length L. The ball is constrained to move on a horizontal, frictionless plain. The cords are stretched to a tension T When t 0, your intrepid instructor gives the ball a very small horizontal displacement x (a) Derive the equation of motion and find expressions for the natural circular frequency, the frequency, and the period of vibration. (b) For m - 2 kg, L 3 m T 300 N and x 30 mm, evaluate the expressions in part (a) and find the balls maximum velocity and acceleration. Hints: For the very small displacement relative to the lengths of the elastic cords, we can neglect the small change in T. Also for very small displacements, sin ? ~-

    A uniform rod with a mass m and length L has one end attached to a pivot. The rod swings around on a frictionless horizontal table with angular speed wo. A ball with mass m (so same mass as the rod) is placed on the table a distance d from the pivot. The ball is made of clay so when the rod strikes it, the ball sticks to the rod (i.e., inelastic collision). If the final (post-collision) angular velocity of...
