1. The problem statement, all variables and given/known data A uniform bar of mass m and length l is suspended on a frictionless hinge. A horizontally launched blob of clay of mass m strikes the bottom end of the bar and sticks to it. After that, the bar swings upward. What is the minimum initial speed v of the blob of clay that would enable the rod to swing a full circle? Which concepts/laws would be most helpful in solving this problem? Select the best answer from the options below. CHOICES kinematics of rotational motion; conservation of energy conservation of momentum, conservation of energy conservation of angular momentum, conservation of momentum conservation of angular momentum, conservation of energy conservation of energy, Newton's laws Newton's laws, conservation of angular momentum conservation of angular momentum, kinematics of rotational motion Newton's laws, kinematics of rotational motion 2. Relevant equations 3. The attempt at a solution I though the answer was momentum and linear momentum because the linear momentum converts into the angular one ,but I am wrong. So, what it the right answer?
