Pivot Rod - 20 Clay о Clay Top View A uniform rod is at rest on a horizontal surface. A student may launch a sphere of clay toward the rod along one of the three paths shown in the figure. Path X and path Z are directed toward the center of mass of the rod. In each case, the sphere of clay is launched with the same linear speed and sticks to the rod. In each case, the time of collision between the sphere of clay and the rod is time to. A pivot is fixed to the end of the rod, representing the point at which the rod or clay- rod system may rotate. Frictional forces are considered to be negligible.
< 7 of 22 > A sphere of clay travels toward the rod along path Z. A student must predict what will happen to the linear momentum and the angular momentum of the rod-sphere system as a result of the collision. Which of the following correctly predicts the change, if any, of these quantities? Linear Momentu Angular Momentu No change No change Linear Momentu m Angular Momentu No change Decreases Linear Momentu Angular Momentu m m Decreases No change Linear Momentu Angular Momentu m Decreases Decreases Submit
