A solid rubber ball with a diameter of $8.0\,\text{cm}$ is let go from rest with the top of the ball $80\,\text{cm}$ above a horizontal surface. It moves straight down and then rebounds so that the greatest height attained by the top of the ball is $45\,\text{cm}$, as shown. If the kinetic energy of the ball is $0.75\,\text{J}$ immediately before it hits the surface, what is its kinetic energy immediately after it has left the surface?
- A$0.36\,\text{J}$
- B$0.39\,\text{J}$
- C$0.40\,\text{J}$
- D$0.42\,\text{J}$
