Answer

Explanation:

Step1: Understand energy at extreme positions

At extreme positions (A and E), the ball is momentarily at rest. So kinetic energy (KE) is 0, and potential energy (PE) is maximum as the ball is at its highest height relative to the lowest - point C.

Step2: Analyze energy at lowest position

At the lowest position C, the ball has maximum speed. So KE is maximum and PE is minimum as the height of the ball above the lowest - point is 0.

Step3: Consider intermediate positions (B and D)

At intermediate positions B and D, the ball has both KE and PE. As the ball moves from A to C, PE is converted to KE, and as it moves from C to E, KE is converted to PE. At B and D, there is a non - zero amount of both KE and PE.

Answer:

Position A: Maximum potential energy, Minimum kinetic energy Position B: Decreasing potential energy, Increasing kinetic energy Position C: Minimum potential energy, Maximum kinetic energy Position D: Increasing potential energy, Decreasing kinetic energy Position E: Maximum potential energy, Minimum kinetic energy
