Calculate the potential energy for each experiment:

Problem: Calculate the potential energy for each experiment.

Given information:

• The ball rolls to a zero height at the end of the descent, so the potential energy at the end of the descent $$E_{p1} = E_{p2} = E_{p3} = 0$$.

Formulas:

• Potential energy is calculated using the formula: $$E_p = mgh$$

Calculations:

1. Experiment 1:
• $$E_{p01} = mgh_{01} = \text{...}$$
2. Experiment 2:
• $$E_{p02} = mgh_{02} = \text{...}$$
3. Experiment 3:
• $$E_{p03} = mgh_{03} = \text{...}$$

Note: The heights ($$h_{01}, h_{02}, h_{03}$$) for the initial potential energy calculation are not provided in the image. Therefore, the potential energy calculations remain as formulas.
