A pendulum bob when released from position X, hits a plastic cup on ground and toppled it to its side.
Which one of the following correctly shows the conversions of energy that took place in this experiment?
A Potential energy of pendulum bob → Kinetic energy of pendulum bob
→ Potential energy of plastic cup → Sound energy
B Potential energy of pendulum bob → Kinetic energy of pendulum bob → Kinetic energy of plastic
cup → Sound energy
C Kinetic energy of pendulum bob → Potential energy of plastic cup → Sound energy
D Kinetic energy of pendulum bob → Potential energy of pendulum bob → Kinetic energy of plastic
cup → Sound energy
