Chapter 9: Q18E (page 343)
Consider the following diagram when answering thequestions on the next page.
a. Compare balls A and B in terms of potential energy in both the initial and final setups.
b. Ball A has stopped moving in the final setup, but energy must beconserved. What happened to the potential energy of ball A?
Short Answer
a.
In the initial, ball A has higher potential energy.
In the final, ball B is having higher potential energy.
b.
After the motion of A, its kinetic energy increases, and the P.E decreases.
