A Point B
B Point A
C Halfway between B and C
D Point C

Worked Solution

Step 1: Point A is the highest point (Max GPE). Step [2-9]: As the ball rolls down to B, GPE is converted to kinetic energy. Step [2-9]: Point B is the lowest point, where the conversion to kinetic energy is maximum.

Correct answer: Point B
