A vertical uniform rod of length L is attached to a pivot P at the top end. A small ball of mass m is moving horizontally to the right with velocity v toward the bottom end of the rod. A dashed line shows the ball's path toward the tip of the rod.
A ball of mass m striking the bottom end of a pivoted rod of mass M.
A small ball of mass \(m\) travels horizontally with speed \(v\) on a frictionless surface. It strikes the bottom end of a uniform rod of mass \(M\) and length \(L\) that is suspended vertically from a frictionless pivot at its top end. The ball sticks to the rod, and the ball-rod system begins to rotate about the pivot. Which of the following correctly compares the linear momentum of the ball-rod system immediately before the collision, \(p_i\), to the linear momentum of the system immediately after the collision, \(p_f\), and provides the correct physical justification?
