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.
Consider the situation in which three identical spheres of clay are launched simultaneously, one along each possible path. All three spheres of clay are launched with the same initial linear speed and collide with the rod at the same time. The time of collision with the rod for each sphere is time to Which of the following predictions is correct about the motion of the system containing the rod and all three spheres of clay immediately after the collision? The system will rotate in the clockwise direction with a constant angular speed. The system will rotate in the counterclockwise direction with a constant angular speed. The system will rotate in the clockwise direction with a changing angular speed. The system will rotate in the counterclockwise direction with a changing angular speed. Submit
