Answer

Explanation:

Step1: Recall energy - conversion in a pendulum

At the highest points (A and C), the pendulum is momentarily at rest. So, the kinetic energy (KE) is zero and the potential energy (PE) is maximum. At the lowest point (B), the pendulum has its maximum speed, so the kinetic energy is maximum and the potential energy is minimum.

Step2: Match the energy - bar charts

The first bar - chart with more KE and less PE corresponds to point B. The second bar - chart with almost zero KE and maximum PE corresponds to points A and C. The third bar - chart with more KE and less PE also corresponds to point B.

Answer:

First bar - chart: B Second bar - chart: A or C Third bar - chart: B
