A Metal Bar Is Hanging from a Hook in the Ceiling

question 1

Multiple Choice

A metal bar is hanging from a hook in the ceiling when it is suddenly struck by a ball that is moving horizontally (see figure) . The ball is covered with glue, so it sticks to the bar. During this collision

• A) the angular momentum of the system (ball and bar) is conserved about the hook because only gravity is acting on the system.
• B) the angular momentum of the system (ball and bar) is not conserved because the hook exerts a force on the bar.
• C) the angular momentum of the system (ball and bar) is conserved about the hook because neither the hook nor gravity exerts any torque on this system about the hook.
• D) both the angular momentum of the system (ball and bar) and its kinetic energy are conserved.
• E) both the linear momentum and the angular momentum of the system (ball and bar) are conserved.
