Pivot A uniform rod of length L and mass m is pivoted about the point shown in the diagram above. 1. Write an equation for the rotational inertia of the rod about the specified pivot point. 2. Suppose the rod is released from rest when the main axis is horizontal, as shown in the diagram above. Calculate the maximum angular velocity achieved by the rod. mass The rod collides with a mass that can be modeled as a point mass m as shown in the diagram above. As a result of the collision the rod stops. 3. Write an equation describing the velocity of the point mass m after the collision.
