# Ball Energy

APPH12-9EKJ9L

A ball is spun attached to a massless string that is very much longer than the diameter of the ball, with an angular velocity $\omega_{0}$. The mass of the ball magically doubles while the angular velocity and the string remain unchanged.

What conclusions can be drawn?

A

The kinetic energy of the larger ball is increased but the angular momentum remains the same.

B

The kinetic energy of the ball and the angular momentum are both increased

C

The kinetic energy of the ball remains the same but the angular momentum increases.

D

Both the kinetic energy and angular momentum of the ball remain the same.
